PURPOSE:To obtain an electrophotographic sensitive body having excellent electrostatic characteristic and moisture resistance by incorporating a specific binder resin into a photoconductive layer and allowing a crosslinking agent to co-exist therein. CONSTITUTION:The binder resin incorporated into the photoconductive layer contains 0.05-10wt.% copolymer component having 1X10<3>-1X10<4> weight average mol. wt. and contg. at least one acidic group selected from a -PO3H2 group, -SO3H group and -COOH group. The binder resin further contains the crosslinking agent and, therefore, the resin of <=10,000 weight average mol. wt. crosslinked by the crosslinking agent is used. The electrostatic characteristics are thereby improved. The electrophotographic sensitive body having the sharp and good-quality image is obtd. even if the environment at the time of forming the copied image fluctuates to a low temp. and low humidity or high temp. and high humidity. |
