フィルタ２に達する。FIG. 1 shows a three-color overlapping color recording apparatus, particularly a color copying machine. In the figure, the light from the exposure lamp 1 is focused by a reflector P, hits the document plate, and is reflected by each mirror ml, m2, . m3. It reaches the color separation filter 2 via m4 and lens t2.

ドラム状の感光体３に到達する。The color separation filter 2 separates the reflected light corresponding to the image density of the document into each color component (blue B1 red R1 green G) and reaches the drum-shaped photoreceptor 3.

紙上に上記のＹ顕像が転写される。A sheet of transfer material, such as a transfer paper, sent out by the paper feed section 5 and the registration roller 6 in time with the exposure is wound around a transfer drum 7 as a transfer material support. Under the discharge action of the transfer charger 8, the above-described Y image is transferred onto this transfer paper.

される。During exposure in the second image forming process, the color separation filter 2 rotates and comes to a position where the R filter blocks the optical path, and exposure with a red (ordinary) light image is performed. Then, development work is performed by the C developing device 4c containing cyan developer, which is a complementary color to red, to produce cyan (C).
g image is formed. This C developed image is transferred to be superimposed on the Y developed image transferred onto the transfer paper in the first transfer operation.

When the first transfer is completed, the transfer paper and the transfer drum 7 are neutralized by the upper and lower separation chargers 14, and are sent to the fixing roller 15 by the conveyor belt v, where they are subjected to heat and pressure to be separated into Y, M, and C. Each developed image is fixed onto the transfer paper to obtain the desired color image.
このように本実施例では、１枚のカラー複写製品を得る
にあたって転写紙、従って転写ドラム７が３回転する。As described above, in this embodiment, the transfer paper, and thus the transfer drum 7, rotates three times to obtain one color copy product.

述したように、クリーニング作業を施こし之としても感
光体上にはわずかの現像剤がどうしても残ってしまう。Now, assuming that the circumference of the photoconductor 3 is the same as the circumference of the transfer drum 7, the photoconductor 3 similarly rotates three times. Then, Y, M, and C images are sequentially formed on the photoreceptor that rotates three times. In this case, no particular problem arises as long as the developer for the image formed on the photoreceptor is thoroughly removed from the photoreceptor before the formation of the next image. However, as described above, even after the cleaning operation is performed, a small amount of developer inevitably remains on the photoreceptor.

Ｃの各顕像のための上記の各作業が行なわれる。In this embodiment, in order to prevent this color mixture from occurring, the circumference of the photoreceptor 3 is set to 3 times the circumference of the transfer drum 7, as shown in FIG.
Further, three portions of the photoreceptor surface corresponding to one rotation of the transfer drum 7 are applied to the image forming process of Y, M, and C images, respectively. That is, in the Y area, charging, exposure, development, and transfer operations for creating a Y image are performed, and in the M and C areas, M,
The above operations for each visualization of C are performed.

品質のカラー画像が得られる。With this configuration, the Y, M, and C developers always adhere only to the Y, M, and C areas, respectively, and do not adhere to other areas. Therefore, a color image of high quality can be permanently obtained without color mixing between the colors. Furthermore, if the formation position of each developing image on the photoreceptor is always set at the same position as in this embodiment, when making multiple copies, the first, second, etc. images are created at the same location on the photoreceptor. Therefore, the second and subsequent images are not affected by the afterimage of the previous image, and sensitivity unevenness does not occur. Therefore, a large number of high quality color images can be obtained.

感光層が設けられている。In addition, the M area, which is imagewise exposed to green light (CG) to create the M microscope image, and the C area, which is imagewise exposed to red light (R) to create the C image, are both made of As2Se3-based materials on an aluminum substrate. A photosensitive layer is provided.

The AS2Se3-based photosensitive material exhibits superior photosensitivity to G and R light.
前述の通り、本実施例では常にＹ領域がＢ光で露光され

ある。As described above, in this embodiment, the Y area is always exposed to B light, the M area is exposed to G light, and the C area is always exposed to R light. These areas are not exposed to any other light. Therefore, by arranging the photosensitive layers in each of these regions as shown in FIG. 2, a high sensitivity state can always be maintained when the photoreceptor 3 is exposed to light of different wavelengths. As a result, high-quality electrostatic latent images are formed on the photoreceptor, and the quality of color images obtained by developing and transferring these images is also good.
更に、露光光の波長に合つ友最適な感光体を使うことに
より、露光ランプ１の電力低下が可能となり、それ故、
省エネルギに供することができる。Furthermore, by using an optimal photoreceptor that matches the wavelength of the exposure light, it is possible to reduce the power of the exposure lamp 1, and therefore,
It can contribute to energy saving.
更に、電力低下により機内の温度上昇が低くおさえられ
、光学系冷却用ファンの風量を低下することもできる。Furthermore, by reducing the power, the temperature rise inside the machine can be kept low, and the air volume of the optical system cooling fan can also be reduced.
この場合には、騒音が低下する。In this case, noise is reduced.
