The display device includes a display portion having a cavity portion surrounded by wall surfaces, at least one part of the wall surfaces being formed of a transparent member and forming a structural color forming surface provided with fine asperities having predetermined regularity, a liquid being hermetically sealed to have a liquid surface in the cavity portion and having a refractive index approximately equivalent to that of the transparent member, an actuator giving a disturbance to the liquid to bring the liquid into contact with the forming surface and a control unit controlling driving of the actuator to switch reflection and transmission characteristics of light when the light is incident into the forming surface, thereby controlling color display using reflected light formed by the forming surface.

A determining unit determines whether a difference between a temperature value and a temperature detected by a temperature detecting unit is equal to or larger than a first value. A pattern forming unit, when the determining unit determines that the difference is equal to or larger than the first value, forms a pattern for measurement including sub-patterns of a plurality of colors on a transfer medium. A calculating unit calculates a misregistration-amount for each sub-pattern based on a detected position of the sub-pattern and a predetermined position of the sub-pattern. A correcting unit corrects a position on which the sub-pattern is to be formed based on the misregistration-amount. An image forming unit forms an image for each color factoring in corrected position for each color.

An image forming apparatus includes: an image carrying member, a toner feeding unit that forms a charged toner on a surface of the image carrying member, a toner image forming unit that forms a reversely charged toner image by applying charge to the charged toner according to image information, the applied charge having a polarity contrary to the charged toner, a color forming information applying unit that applies color forming information to the reversely charged toner image with light, a transferring unit that transfers the reversely charged toner image to a surface of a recording medium, a fixing unit that fixes the reversely charged toner image transferred to the surface of the recording medium, and a color forming unit that forms color of the toner image applied with the color forming information, the charged toner including a first component and a second component that are capable of forming the color upon reaction with each other, and are separated from each other in the toner, and a photo-curable composition containing at least one of the first component and the second component, the reaction for forming the color being controlled by maintaining a cured state or an uncured state of the photo-curable composition by application of color forming information with light.

An optoelectronic display comprising a plurality of pixels, each pixel comprising a plurality of sub-pixels, wherein the optoelectronic display comprises a colour-forming layer which is patterned providing a plurality of discrete colour-forming regions in a two-dimensional array, and wherein an addressing array is provided for addressing the discrete colour-forming regions, at least some of the discrete colour-forming regions having portions which are separately addressable by the addressing array, each portion defining a sub-pixel of the optoelectronic display.
