preparation example Construction

[0216] The method for producing the toner of the present invention is not particularly limited, and known methods can be used, and emulsion polymerization coagulation and emulsion coagulation methods can be suitably used. Hereinafter, among the toner particles, an example of a method for preparing a toner containing particles of an ultraviolet absorber and a colorant will be described.

[0217] The emulsion polymerization coagulation method is a method of preparing toner particles by mixing a dispersion of binder resin particles (hereinafter also referred to as binder resin particles) prepared by emulsion polymerization, ultraviolet absorber particles (hereinafter also referred to as UV absorber particles), dispersions of colorant particles (hereinafter also referred to as colorant particles), and release-type dispersions such as wax, are mixed and aggregated until the toner particles reach the desired particle size , and further shape control is performed by performing fusion...

Abstract

The invention provides an image post-processing method, an image post-processing apparatus and an image forming apparatus for controlling a glossiness of a fixed toner image without influence of the photographic fixing of the toner image. The method includes the steps of: irradiating the fixed toner image formed with a toner containing a compound that absorbs light and fixed on a recording mediumwith a glossiness control light that is capable of at least reducing a glossiness of the fixed toner image, wherein the glossiness control light has a maximum emission wavelength in a wavelength region which is absorbed by the compound.

Description

technical field [0001] The invention relates to an image post-processing method, an image post-processing device and an image forming device. More specifically, the present invention relates to an image post-processing method, an image post-processing apparatus, and an image forming apparatus capable of adjusting the glossiness of a toner image without affecting the fixability of the toner image. Background technique [0002] In recent years, the types of recording media on which images are formed tend to be diversified. For example, in the case of woodfree paper (top quality paper) and coated paper (coated paper), the gloss ( Glossiness) are different. In addition, when a toner image is formed on a recording medium, there is a large difference in glossiness between the portion where the image is formed (image portion) and the glossiness of the background portion (non-image portion) of the recording medium on which no image is formed. May be uncomfortable. [0003] In vie...
