PURPOSE:To obtain an electrophotographic sensitive body which has high mechanical strength and excellent durability and obviates the generation of phase sepn., etc. of the components of a charge transfer layer by forming the charge transfer layer contg. a specific arom. amine compd. and specific polysulfone resin on a charge generating layer on a conductive substrate. CONSTITUTION:The charge transfer layer consisting of the arom. compd. expressed by formula I (Ar1, Ar2, Ar3 are phenyl or heterocycles, these rings may be substd. by (substd.) aryl and Ar1 and Ar2 may form jointly a heterocycle) and the polysulfone resin expressed by formula II (n denotes the degree of polymn. at which the weight average mol.wt. attains about 15,000-70,000) is laminated on the charge generating layer formed on the conductive substrate. The electrophotographic sensitive body which obviates the generation of the phase sepn. of the charge transfer layer and has the high mechanical strength and excellent durability is thus obtd. |
