WET TYPE ELECTROPHOTOGRAPHIC APPARATUS AND PHOTORECEPTOR USED FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To employ a multiplex development system in a wet process electrophotographic technique and to output a color image having high resolution and high image quality at a high speed when a photoreceptor having an organic photosensitive layer as a photosensitive layer is used. SOLUTION: The photoreceptor 10 is used for a wet process electrophotographic apparatus 1 employing the multiplex development system and is equipped with a substrate 101 having a conductive surface, and the organic photosensitive layer 102 which covers the conductive surface and changes in the electrostatic state by irradiation of light. The specific dielectric constantεrof the organic photosensitive layer 102 is <3.5 and the specific dielectric constantεrand the thickness (d) (μm) of the organic photosensitive layer satisfy the relation expressed by inequality: 0.11<εr/d<0.5.
