PURPOSE:To obtain an electrophotographic sensitive body unnecessary for maintenance and prevented from interference by irradiating the surface of an electrostatic charge generating layer with laser beams to the wavelength region of which this layer has sensitivity to form fine roughness, and laminating a charge transfer layer thereon. CONSTITUTION:An intermediate layer 2, when needed, is formed on a conductive substrate 1, and on this layer 2 the charge generating layer 3 and the charge transfer layer 4 are laminated to form an electrophotographic sensitive body for use in a laser beam printer. The conductive substrate is prepared by forming, when needed, a coating layer 5 contg. a phenol resin or the like and a conductive pigment or the like dispersed into said resin on a base 6 made of aluminum or the like. The intermediate layer 2 is, preferably, made of a polyamide resin or the like with a film thickness of 0.2-10mum, and the charge generating layer 3 is formed by dispersing a pigment or dye into a binder resin. The charge transfer layer 4 is made of a hole transfer material, such as a compd. contg. N-contg. cyclic compd. or hydrazone compd. by dissolving it in a film- forming resin soln. |
