Title:
電子写真用感光体およびそれを搭載した電子写真装置
Document Type and Number:
Japanese Patent JP7187958
Kind Code:
B2
Abstract:
An electrophotographic device equipped with a negatively-charged laminated electrophotographic photoreceptor that can be charged by a scorotron charging method, and includes a conductive substrate, and a charge generation layer and a charge transport layer sequentially provided on the conductive substrate, wherein the charge generation layer contains a charge generation material and a resin binder that is a poly(vinyl butyral) resin binder, and the charge transport layer contains a charge transport material that is either or both of stilbene compounds represented by Formula (1) and Formula (2), a binder resin, and an oxidation inhibitor that is tribenzylamine represented by Formula 3, wherein the conductive substrate is cylindrical, the electrophotographic photoreceptor has a difference between a maximum value and a minimum value of a surface potential in a circumferential direction, after exposure to ozone at an exposure dose of 100 ppm·h, that is 12 V or less.
