ELECTRO-PHOTOGRAPHIC PHOTO-SENSITIVE UNIT, A PROCESS CARTRIDGE, AND AN ELECTRO-PHOTOGRAPHIC APPARATUS CAPABLE OF OVERCOMING IMAGE DETERIORATION PROBLEMS RELATED TO A GHOST PHENOMENON

摘要

PURPOSE: An electro-photographic photo-sensitive unit, a process cartridge, and an electro-photographic apparatus are provided to eliminate or reduce image defects due to a ghost phenomenon under low temperatures and low humidity in addition to high temperatures and high humidity.;CONSTITUTION: An electro-photographic photo-sensitive unit includes a support, an electric charge generating layer, and an electric charge transferring layer. The electric charge generating layer and the electric charge transferring layer are formed on the support. The electric charge generating layer includes an electric charge generating material and an amine compound represented by chemical formula 1. In the chemical formula 1, the R1 to R10 are respectively hydrogen, halogen, hydroxyl group, carboxylic group, alkoxycarbonyl group, aryloxycarbonyl group, substituted or non-substituted acyl group, substituted or non-substituted alkyl group, substituted or non-substituted alkoxy group, substituted or non-substituted aryloxy group, substituted or non-substituted amino group, or substituted or non-substituted cyclic amino group. The X1 is carbonyl group or dicarbonyl group.;COPYRIGHT KIPO 2012
