Title:
ELECTROPHOTOGRAPHIC PHOTORECEPTOR, ELECTROPHOTOGRAPHIC PHOTORECEPTOR CARTRIDGE, AND IMAGE FORMATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/193678
Kind Code:
A1
Abstract:
The present invention provides a positively-charged monolayer-type electrophotographic photoreceptor that has an outermost layer, the electrophotographic photoreceptor having excellent mechanical strength, electric characteristics, and adhesiveness, and also provides an electrophotographic photoreceptor cartridge and an image formation device. The problem described above is solved by providing a positively-charged electrophotographic photoreceptor that has a monolayer-type photosensitive layer and an outermost layer, wherein the Martens hardness of the surface of the photoreceptor satisfies a prescribed condition, and preferably, the contents and molecular weights of a hole transport material and an electron transport material contained in the photosensitive layer satisfy a specific relational expression.
