となる。The paper 11 to which multiple colors of toner have been transferred in the above development and transfer process is neutralized by a corotron 16, and then removed from the gripper 13a by a peeling solenoid 17 and fixed! +9, and the toner image is fixed onto the paper 11 between the heating roll 20 and pressure roll 21 of the fixing device 19. Also, the toner image before fixing is transferred to the entire paper 11 as shown in FIG. Other colored toners 26 are layered one after another on the colorless and transparent toner 25 transferred to the colorless transparent toner 25, and when this is fixed by heat and pressure in the fixing device 19, the colorless and transparent toner 25 in the lowest layer is layered on the permeation layer. Other colored toners can play a role

のを示す。In this case, the image becomes uneven and reduces the image glossiness, but by transferring the colorless transparent toner 25 to the bottom layer as in this invention, the unevenness of the image becomes /2 to 173 compared to the conventional one, and all It is embedded in the transparent toner 25 with an area of 1.5 mm as shown at 26' in Fig. 5←), and this trap cancels out the fluidity of the colorless transparent toner 25 and the colored toner 26, so that the copy image differs from the original image. can be prevented from expanding. Note that FIG. 5(b) shows an enlarged version of the conventional copy image.
また第３図にこの発明の画像形成方法で得られた画像と
従来のものの比較を示す。Further, FIG. 3 shows a comparison between an image obtained by the image forming method of the present invention and a conventional method.
この図から明らかなように従来のものに比べて画像拡大

ても同様な効果が得られる。On the other hand, on the machine of this invention, the colored toner is surrounded by colorless transparent toner to suppress the enlargement of the image after fixing, and to increase the glossiness of the image by reducing the difference between the layers of toner images. Therefore, the same effect can be obtained by developing only the non-image area with a colorless transparent toner and transferring it to paper II.

を無色透明トナーで現像することも可能である。As a method, for example, as shown in FIG. 6, the colored toner and the colorless transparent toner may be charged to opposite polarities (colored toner: 1, colorless and transparent toner: +), or even if they have the same polarity, the amount of charge may be different. By selecting and configuring the materials so that they appear to be charged with the same polarity but with opposite polarity when a developing bias is applied, colored toner and colorless transparent toner can be stored in the same developing device, and the image area can be It is also possible to develop with colored toner and non-image areas with colorless transparent toner.
この場合転写には中間転写方式を採用する必要がある。In this case, it is necessary to adopt an intermediate transfer method for transfer.
これは有色トナーと無色透明トナーの転写電界が異なる
ため、コロトロ／による転写ができない丸めである。This is because the transfer electric fields of the colored toner and the colorless transparent toner are different, so it is a round shape that cannot be transferred by Corotro/.

１１へ定着される。As for the development and transfer method, the non-image area of the electrostatic latent image formed on the surface of the photoreceptor 1 by exposure to light is developed with colorless transparent toner contained in the developing device 5 or δ, and the image area is developed with colored toner. The diameter of the hole is transferred to the intermediate transfer roll 30, and furthermore, at the position where the intermediate transfer roll 30 and the transfer drum 13' are in contact, the image is thermally transferred to the paper 11 that is attracted to the transfer drum 13' and conveyed. , and Paper II
The toner image transferred to is sent to the fixing device 19 and fixed onto the paper 11.

下が少ない良好なカラー複写が得られるようになる。Effects of the Invention As described in detail above, in this invention, since the colored toner image forming the image is surrounded by the colorless transparent toner, the fluidity of the colored toner and the fluidity of the colorless and transparent toner are mutually matched during fixing. Since the images cancel each other out, it is possible to prevent the image obtained after fixing from being enlarged compared to the image of the original.In addition, like a halftone image, the halftone area and the paper surface coexist, which becomes uneven and glossy. Even if the gloss level is lowered, the level difference between the concave and convex portions is smaller than that of the conventional type, so it is possible to obtain good color copies with less decrease in gloss level.

実施することが可能である。In addition, since both the image and non-image areas are formed with toner, there is no difference in gloss between the image and non-image areas, and this makes it possible to obtain good-looking copies even when using plain paper, making it economical. At the same time, compared to spraying or coating the entire paper with transparent resin, there is no need to incorporate a complicated mechanism into the copying machine, so it can be implemented easily and inexpensively.
