Title:
ELECTROPHOTOGRAPHIC PHOTORECEPTOR, ELECTROPHOTOGRAPHIC PHOTORECEPTOR CARTRIDGE, AND IMAGE FORMING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/201007
Kind Code:
A1
Abstract:
Provided is a novel negative-charge type electrophotographic photoreceptor which has a cured resin-based protective layer and does not require a heating treatment for enhancing electrical properties. The negative-charge type electrophotographic photoreceptor comprises, on a conductive support body and in this order: a photosensitive layer; and a protective layer containing a cured product obtained by curing a curable compound. The photosensitive layer contains at least a hole transport material (HTM) and a radical acceptor compound or an electron transport material (ETM). The hole transport material (HTM) is a compound in which the energy difference between the HOMO level and LUMO level is 3.60 eV or less, and the HOMO level is -4.50 or less using the vacuum level as a basis.
