electrophotographic photoreceptor using the α- phenyl stilbene compounds, as well as an image forming apparatus and an image forming apparatus for a process cartridge using it

摘要

PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor having superior high-speed responsiveness and high sensitivity, an image forming apparatus using the same, and a process cartridge for the image forming apparatus.;SOLUTION: In the electrophotographic photoreceptor including at least a photosensitive layer on a conductive support, the photosensitive layer includes an α-phenylstilbene compound represented by general formula (I), where R₁, R₂, R₃, and R₄ represent an alkyl group or substituted or unsubstituted aryl group, Ar₁ represents substituted or unsubstituted arylene group, and R₅ represents hydrogen atom, alkyl group, alkoxy group, or substituted or unsubstituted aryl group.;COPYRIGHT: (C)2010,JPO&INPIT
