ELECTROPHOTOGRAPHIC PHOTO-SENSITIVE MEMBRANE, A PROCESS CARTRIDGE, AND AN ELECTROPHOTOGRAPHIC APPARATUS CAPABLE OF OVERCOMING GHOST PHENOMENON AND SUPPRESSING DARK PIXELS

摘要

PURPOSE: An electrophotographic photo-sensitive membrane, a process cartridge, and an electrophotographic apparatus are provided to form an intermediate layer on a conductive support and to form a photo-sensitive layer on the intermediate layer.;CONSTITUTION: An electrophotographic photo-sensitive membrane includes a conductive support, an intermediate layer, and a photo-sensitive layer. The intermediate layer is formed on the conductive support. The photo-sensitive layer is formed on the intermediate layer. The photo-sensitive layer includes electric charge generating materials and hole transporting materials. The intermediate layer includes metal oxide particles and compound with a structure which is represented by chemical formula 1. In chemical formula 1, R1 and R3 are respectively halogen elements, C1 to C6 alkyl groups, acetyl groups, C1 to C6 halogenated alkyl groups, or COOR4; R4 is a C1 to C6 alkyl group; k, l, and m are respective the integer of 0 to 3; R2 is halogen element, a C1 to C6 alkyl group, an acetyl group, a C1 to C6 halogenated alkyl group, COOR8, or a monovalent group with a structure represented by chemical formula 2 or 3; and R8 is a C1 to C6 alkyl group.;COPYRIGHT KIPO 2012
