摘要： PROBLEM TO BE SOLVED: To improve electrifying ability and sensitivity, to reduce optical memory and image flowing and to improve image quality in an amorphous silicon- based electrophotographic photoreceptor for negative electrification.
SOLUTION: At least a lower part charge injection preventing layer 107 and a photoconductive layer 103 comprising a first photoconductive layer 104 and a second photoconductive layer 105 are laminated on an aluminum-based base body 101 on which a silicate film 108 is formed. The lower part charge injection preventing layer 107 is prepared by using a non-single crystal silicon film free from doped impurities, whose base material is silicon containing at least one of nitrogen, oxygen, hydrogen and halogens, and the photoconductive layer 103 is prepared by using a non-single crystal silicon film whose base material is silicon containing at least one of hydrogen and halogens. Further, the first photoconductive layer 104 is obtained by incorporating at least one kind of atom in the group 15 into the silicon in an amount of 0.01 to 10 atom ppm, and the second photoconductive layer 105 is obtained by incorporating at least one kind of atom of the group 13 into the silicon in an amount of 0 to 15 atom ppm.
