[0330] -Preparation of various dispersions-

[0331] Next, methods for preparing various dispersions used in the toner production process using the above-mentioned emulsification aggregation method will be described below.

[0332] The resin particle dispersion is prepared by dispersing resin particles prepared by emulsion aggregation or the like in a solvent using an ionic surfactant. Alternatively, the resin particle dispersion is prepared by dissolving the resin particles in a solvent capable of dissolving the resin therein, followed by inverse emulsification. Incidentally, examples of the dispersion medium in the resin particle dispersion include aqueous media and organic solvents.

[0333] In addition, by dispersing a surface lubricant in water together with an ionic surfactant or a high-molecular-weight electrolyte (for example, a high-molecular-weight acid and a high-molecular-weight base), and heating the dispersion at the melting point or higher, a stronger It was g...

example 1

[0605] (image formation)

[0606] The image forming apparatus illustrated in FIG. 1 was prepared, and Developer 1 was used as a developer.

[0607] A dielectric drum in which a transparent dielectric layer (acrylic resin layer) with a thickness of 20 μm was formed on the periphery of an aluminum tube stock drum with a diameter of 30 mm (95% reflectance) was used as the image carrier 10 .

[0608] As the electrostatic latent image forming device 12 , an ion flow control head having control slits (control electrodes provided with slits) arranged on the entire surface of a corona charger (ion generating region) at a resolution of 600 dpi was used.

[0609] The developing device 14 is a developing device equipped with a metal sleeve for two-component magnetic brush development and capable of reverse development. Incidentally, when the above-mentioned developer 1 was poured into this developing unit, the toner charge amount was about -5 to -30 µC / g.

[0610] The color informatio...

example 2

[0632] Image formation was performed in the same manner as in the image formation process in Example 1 except that the linear speed of the image carrier 10 was changed to 300 mm / sec, and images were evaluated in the same manner as in Example 1. Furthermore, the fixing means and the light irradiation means were removed, whereby an unfixed image was output under the same conditions. After allowing it to stand in a dark place for 10 minutes, fixing and light irradiation were performed at the same speed and temperature to undergo image formation.

[0633] As a result, a printed matter was obtained which was by no means inferior to the printed matter in Example 1 in terms of color development density, color reproducibility, and highlight image portion reproducibility (regardless of the presence or absence of standing).

Abstract

The invention provides an image forming apparatus, an image forming method and toner. The image forming apparatus includes an image carrier; an electrostatic latent image forming unit; a developing unit; a color information applying unit; a transfer unit; a fixing unit; and a color forming unit, the toner containing a first component and a second component that are present in an isolated state from each other and that can form the color upon reaction with each other, and a photocurable composition containing at least one of the first component and the second component, the photocurable composition keeping a cured or uncured state by being applied the color.

Description

technical field [0001] The present invention relates to an image forming apparatus and an image forming method, each of which uses an electrostatic recording system. Specifically, the present invention relates to a toner that can develop colors in different colors from each other when exposed to light of different wavelengths, and to an image forming apparatus and an image forming method using the toner . Background technique [0002] Hitherto, in a recording apparatus for acquiring a color image by an electrophotographic system, basic three primary colors are developed corresponding to respective image information, and the resulting toner images are sequentially superimposed to acquire a color image. As a specific device configuration, a so-called four-cycle machine is known, which repeatedly develops a photoreceptor drum on which a latent image is formed by an image forming method for each color , and transfer the developed image to a transfer member to obtain a color im...
