Electrophotographic photosensitive member, process cartridge and electrophotographic apparatus

摘要

In order to provide an electrophotographic photosensitive member with which a ghost is suppressed even under a low temperature and low humidity environment, and a process cartridge and an electrophotographic apparatus having the electrophotographic photosensitive member, the electrophotographic photosensitive member has a support, an undercoat layer formed on the support, and a photosensitive layer formed on the undercoat layer and comprising a charge generating material and a hole transporting material, wherein the undercoat layer comprises a particular amine compound.

主权项

1. An electrophotographic photosensitive member comprising a support, an undercoat layer formed on the support, and a photosensitive layer formed on the undercoat layer and comprising a charge generating material and a hole transporting material, wherein
the undercoat layer comprises an amine compound represented by the following formula (1): where, in the formula (1), R1 to R10 each independently represent a hydrogen atom, a halogen atom, a hydroxy group, a carboxyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, a substituted or unsubstituted acyl group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted aryloxy group, a substituted or unsubstituted amino group, or a substituted or unsubstituted cyclic amino group, provided that at least one of R1 to R10 represents a substituted or unsubstituted morpholino group or a substituted or unsubstituted 1-piperidyl group; and X1 represents a carbonyl group or a dicarbonyl group.
