Title:
ELECTROPHOTOGRAPHIC PHOTORECEPTOR AND IMAGE FORMING METHOD
Document Type and Number:
Japanese Patent JP3230178
Kind Code:
B2
Abstract:
PURPOSE: To obtain an electrophotographic photoreceptor very hardly generating interference fringes even if a laser light, source is used, not causing trouble such as the occurrence of voids and black spots or the lowering of density, ensuring high productivity and hardly lowering image quality or sensitivity even after use over a long period of time.
CONSTITUTION: In this electrophotographic photoreceptor obtd. by successively laminating an electric charge generating layer and an electric charge transferring layer on an electric conductive substrate, this Al substrate has 0.11-0.8μm depth Rp of parallel recesses and 0.2-1.6μm max. height Rmax of a roughness curve or 0.20-1.50μm ten-point average surface roughness Rz when the surface roughness of the substrate is measured and the electric charge generating layer contains at least a perylene dye represented by formula I or II, wherein Z is a group of atoms required to form an optionally substd. hetero ring.
