ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER, MANUFACTURING METHOD OF ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER, PROCESS CARTRIDGE AND ELECTROPHOTOGRAPHIC APPARATUS, AND A SOLID SOLUTION AND MANUFACTURING METHOD OF A SOLID SOLUTION

摘要

The present invention provides an electrophotographic photosensitive member which can output images with reduced image defects due to ghosting not only under a normal temperature and normal humidity environment but also even under a low temperature and low humidity environment as especially severe conditions, and a manufacturing method thereof; and a process cartridge and an electrophotographic apparatus each having the electrophotographic photosensitive member. Accordingly, the electrophotographic photosensitive member of the present invention having a support and a photosensitive layer on the support includes the photosensitive layer which contains a solid solution of hydroxygallium phthalocyanine and a compound represented by the following Formula (1) or Formula (1)′, the solid solution having peaks at Bragg angles 2θ of 7.4°±0.3° and 28.3°±0.3° in CuKα characteristic X-ray diffraction.;

1. An electrophotographic photosensitive member comprising a support and a photosensitive layer on the support;
the photosensitive layer comprising a solid solution of hydroxygallium phthalocyanine and a compound represented by the following Formula (1) or Formula (1)′; the solid solution having peaks at Bragg angles 2θ of 7.4°±0.3° and 28.3°±0.3° in CuKα characteristic X-ray diffraction: wherein M represents a metal atom which may have an axial ligand; X represents a carbon atom or a nitrogen atom; R1 to R12 each independently represent a hydrogen atom, a substituted or unsubstituted aryl group, or a substituted or unsubstituted a heterocyclic group, with the proviso that in the case of X being a nitrogen atom, the ring is closed and none of substituents R1 to R4 exists.
