Abstract
An electrophotographic photosensitive member having a support and a photosensitive layer formed on the support, wherein the photosensitive layer contains a boron complex which is a product of the reaction of a compound having a phenolic hydroxyl group and a carbonyl group with a boron halide. Also disclosed are a process cartridge and an electrophotographic apparatus which have such an electrophotographic photosensitive member.
Claims8
An electrophotographic photosensitive member comprising a support and a photosensitive layer formed on the support,
- wherein the photosensitive layer contains a charge-generating material and a boron complex,
- wherein the charge-generating material is an oxytitanium phthalocyanine or a gallium phthalocyanine, and
- wherein the boron complex is a compound represented by any of the following general formulas (2) to (5):
- where R8 to R30 each independently represent a hydrogen atom, a nitro group, a hydroxyl group, an alkyl group, an alkoxyl group, a phenyl group or a tolyl group;
- and R8 to R30 may combine with another adjacent group among R8 to R30 to form a divalent group represented by —CH═CH—CH═CH—.
