Title:
ELECTROPHOTOGRAPHIC PHOTOSENSITIVE BODY
Document Type and Number:
WIPO Patent Application WO/2008/018467
Kind Code:
A1
Abstract:
Disclosed is an electrophotographic photosensitive body which is remarkably
improved in pencil scratch resistance and wear resistance. Specifically disclosed
is an electrophotographic photosensitive body wherein a polycarbonate resin
having a structural unit (1) represented by the formula below is used as a binder
resin for a photosensitive layer (or for a charge-transporting layer in case
of multilayer type) which is formed on a conductive base. [chemical formula
1] (1) (In the formula, R1-R30 respectively
represent a hydrogen atom or a substituent selected from the group consisting
of fluorine, chlorine, bromine, iodine, an alkyl group having 1-17 carbon atoms,
an aryl group having 6-12 carbon atoms, an alkoxy group having 1-5 carbon atoms,
an alkenyl group having 2-12 carbon atoms and an aralkyl group having 7-17 carbon
atoms.)
