Title: Photoreceptor for electrophotography
Inventor: SAKUMA SEIICHI
IPC: G03G15/05
Filed: 1978-08-25
Abstract: PURPOSE: To decrease dark attenuation with respect to primary charging in repetitive two-color process, quicken the charging speed, and achieve easy application of surface potential, by laminating two different photoconductive layers.  
     CONSTITUTION: A first photoconductive layer 12 having sensitivity to color A, and a second photoconductive layer 13 consisting of coloring material containing layer (excluding CdS) which transmits the light of color A and generates charge carrier by the light of color B and a transparent Hall transfer layer are laminated on the surface of a conductive substrate 11. This photoreceptor 1 is negatively charged by a charger 3 under the uniform exposure of the light of color A, and a positive charge is induced in the boundary surface between the layer 12 and layer 13. Then, after positive charge by a charger 3, a white picture image exposure is applied. In the position corresponding to the white ground of the original, the surface potential becomes about 0, and the positive surface charge is preserved in the unexposed part. In the position corresponding to color A, only the layer 13 is made to conduct by the reflected light of color A, and the negative surface potential emerges. The individual formed latent images are developed by developers TA, TB of the reverse polarity of the latent images.
