ELECTROPHOTOGRAPHIC PHOTORECEPTOR, ELECTROPHOTOGRAPHIC METHOD, ELECTROPHOTOGRAPHIC SYSTEM, AND PROCESS CARTRIDGE FOR IT

摘要

PROBLEM TO BE SOLVED: To provide a photoreceptor that has a layer distributing metal oxide and a photosensitive layer on the conductive support, especially a photoreceptor that has a layer distributing metal oxide and a photosensitive layer on the conductive support, and is hard to make defective images having dark spots even after use for a long time. SOLUTION: In a photoreceptor having a layer distributing metal oxide and a photosensitive layer on a conductive substrate, formula (1) shows the dark decay speed of the photoreceptor electrified at a dark place. In the formula, E is an electric field (voltcm-1), And the electric field here is a value obtained by dividing the potential of the photoreceptor by its thickness. T represents time (second). This photoreceptor is featured in that the inclination m of formula (1) is 0.006 (cm1/2volt-1/2) or less when 760 V1/2cm-1/21/2<1000V1/2cm-1/2. COPYRIGHT: (C)2005,JPO&NCIPI
