ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER, PROCESS CARTRIDGE, ELECTROPHOTOGRAPHIC APPARATUS, AND GALLIUM PHTHALOCYANINE CRYSTAL

摘要

Provided is an electrophotographic photosensitive member, a process cartridge and an electrophotographic apparatus each having the electrophotographic photosensitive member that can output an image having less image defects due to a ghost phenomenon not only under a normal-temperature, normal-humidity environment but also under a low-temperature, low-humidity environment as a particularly severe condition. The electrophotographic photosensitive member includes a support and a photosensitive layer formed on the support, in which the photosensitive layer includes a gallium phthalocyanine crystal containing a specific amine compound in itself.

主权项

1. An electrophotographic photosensitive member, comprising:
a support; and a photosensitive layer formed on the support, wherein the photosensitive layer comprises a gallium phthalocyanine crystal in which an amine compound represented by the following formula (1) is contained: in the formula (1): R1 to R10 each independently represent one of a hydrogen atom, a halogen atom, 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, an amino group having a substituent, and a substituted or unsubstituted cyclic amino group, provided that at least one of R1 to R10 represents one of an amino group substituted with a substituted or unsubstituted aryl group, an amino group substituted with a substituted or unsubstituted alkyl group, and a substituted or unsubstituted cyclic amino group; and X1 represents one of a carbonyl group and a dicarbonyl group.
