Title:
ELECTROPHOTOGRAPHIC PHOTORECEPTOR, METHOD FOR MANUFACTURING SAME, AND ELECTROPHOTOGRAPHIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/159342
Kind Code:
A1
Abstract:
The present invention provides: an electrophotographic photoreceptor which, even when a protective layer is provided on a photosensitive layer, shows a high sensitivity and a low residual potential, has an excellent anti-frictional performance and anti-contamination performance, is unlikely to cause optical fatigue and filming, and exhibits an excellent potential stability before and after repeated printing; a method for manufacturing the electrophotographic photoreceptor; and an electrophotographic device. This electrophotographic photoreceptor comprises a conductive substrate, and a photosensitive layer provided on the conductive substrate. The photosensitive layer contains: a hole transportation material having a structure represented by general formula (1); a binder resin having a repetition structure represented by general formula (2); and at least one of electron transportation materials having structures represented by general formulae (ET1)-(ET3).
