Title:
ELECTROPHOTOGRAPHIC PHOTORECEPTOR, METHOD FOR PRODUCING SAME, AND ELECTROPHOTOGRAPHIC DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/154739
Kind Code:
A1
Abstract:
Provided are: an electrophotographic photoreceptor that makes it possible to stably obtain high image quality in all environments, while preventing the occurrence of small black dots and colored spots during initial printing in a high-temperature, high-humidity environment; a method for producing the same; and an electrophotographic device using the same. A positive charging photoreceptor comprising a conductive support body 1, and a photosensitive monolayer 3 provided on the conductive support body and containing a charge-producing material, a hole transport material, an electron transport material, and a binding resin, wherein the binding resin contains a polycarbonate resin, and the moisture vapor transmission rate of the binding resin is in the range of 5-13 g/m2 · day. A positive charging photoreceptor comprising a conductive support body, a charge transport layer provided on the conductive support body and containing a hole transport material and a binding resin, and a charge-producing layer provided on the charge transport layer and containing a charge-producing material, a hole transport material, an electron transport material, and a binding resin, wherein the binding resin of the charge-producing layer contains a polycarbonate resin, and the moisture vapor transmission rate of the binding resin in the charge-producing layer is in the range of 5-13 g/m2 · day.
