Provided is a toner that comprises a binder resin, a releasing agent, and a colorant, wherein the mass average particle diameter of the toner is 3 μm to 8 μm, the content of particles having a particle diameter of no more than 5 μm is from 60% by number to 90% by number, the binder resin comprises a polyester resin (A) having a softening temperature Tm(A) from no lower than 120° C. to no higher than 160° C. and a polyester resin (B) having a softening temperature Tm(B) from no lower than 80° C. to lower than 120° C., and at least one of the polyester resins (A) and (B) is prepared by condensation polymerization between an alcohol component and a carboxylic acid component, and the alcohol component comprises divalent alcohol of 1,2-propanediol in a content of no less than 65% by mole and consists substantially of aliphatic alcohol; and also provided is a developer that comprises the toner and a carrier.

The invention discloses a pixel structure and an organic light emitting display adopting the same. The pixel structure comprises a plurality of pixel units, wherein each pixel unit takes a rhombus structure formed by an upper half part and a lower half part; the adjacent pixel units are arranged in a staggered manner; each pixel unit comprises a plurality of sub pixels; a first sub pixel forms one of the upper half part and the lower half part of the rhombus pixel unit; a second sub pixel and a third sub pixel are arranged side by side to form the other of the upper half part and the lower half part of the rhombus pixel unit together; pixels in the same color of the pixel units in the adjacent rows are arranged adjacently. By integrating the same sub pixels together, the width of the corresponding vapor deposition Mask hole diameter can be enlarged, the difficulty of the Mask technology can be reduced, and the display PPI (Pixel Per Inch) can be improved; meanwhile, because of the staggered arrangement manner of the pixel units in the adjacent rows, the adjacent edges of the second sub pixel and the third sub pixel with the first sub pixel can be longer, main light emitting of the pixel units can be relatively concentrated, and the light mixing effect is good.

In printing of multi-level darkness / lightness of a certain color, which is performed with a dark ink and a light ink of the certain color, graininess is improved. A printing method includes generating a plurality of types of drive signals, and ejecting the dark ink and the light ink from a head, an amount of each ink varying for each dot tone value. In generation of a plurality of the types of the drive signals, a plurality of the types of drive signals are generated, where a waveform section that is for the dark ink of the certain color and that corresponds to a minimum dot tone value in ejection of ink is different from a waveform section that is for the light ink of the certain color and that corresponds to the minimum dot tone value, and where a waveform section that is for the dark ink of the certain color and that corresponds to a maximum dot tone value is different from a waveform section that is for the light ink of the certain color and that corresponds to the maximum dot tone value. In ejection of the dark ink and the light ink from the head, a drive signal that is generated based on a type of the dot tone value designated according to a size of a to-be-formed dot and based on a type of the ink is applied to an element that is provided on the head and that performs an operation for ejecting ink.

In an aspect, a first ink amount relating to the yellow ink is smaller than both a second ink amount relating to the cyan ink and a third ink amount relating to the magenta ink.In another aspect, a first total increase amount is larger than both a second total increase amount and a third total increase amount. The first total increase amount is a total increase amount of inks other than the yellow ink relating to a black yellow gradation. The second total increase amount is a total increase amount of inks other than the cyan ink relating to a black cyan gradation. The third total increase amount is a total increase amount of inks other than the magenta ink relating to a black magenta gradation.In another aspect, a first lowest brightness is lower than both a second lowest brightness and a third lowest brightness. The first lowest brightness is lowest brightness of color to be printed without using black ink on a black yellow gradation. The second lowest brightness is lowest brightness of color to be printed without using black ink on a black cyan gradation. The third lowest brightness is lowest brightness of color to be printed without using black ink on a black magenta gradation.

An image that is robust against position shift and that has improved graininess is formed. In the embodiments, a halftone processor creates a first dot arrangement and a second dot arrangement from related weighting functions and weighting maps (S1508, S1509), evaluates the image quality when the first dot arrangement and the second dot arrangement are overlapped and combined (S1511, S1512), updates the weightings for only pixels where a dot is arranged in case where the evaluation results in the evaluating step are not within a specified range (S1513), obtains a first dot arrangement and a second dot arrangement that were recreated based on the updated weightings (S1508, S1509), and repeats steps S1508 to S1514 until it is determined that the change in image quality due to position shift when the recreated first and second dot arrangements are overlapped and combined is within a specified range.

A toner comprising a toner particle containing a resin and a colorant, wherein, with respect to a temperature-storage elastic modulus curve obtained by powder dynamic viscoelastic measurement on the toner, (I) the relative minimum values for the variation in the storage elastic modulus E′ with respect to temperature T in the temperature range of at least 30° C. and not more than 180° C. have a relative minimum value of equal to or less than −1.00×107 and the relative minimum value on the lowest temperature side is equal to or less than −1.00×108; (II) the storage elastic modulus E′ (50) of the toner at 50° C. is at least 1.00×109 and not more than 9.00×109; and (III) for a storage elastic modulus E′ (120) of the toner at 120° C., E′ (50) and E′ (120) satisfy 1.50≤[E′ (50)] / [E′ (120)]≤3.00.
