PURPOSE: To obtain an electrophotographic sensitive body having high sensitivity and low residual potential, and improved charge receiving capacity, wear resistance, and resistance to environmental changes by incorporating a specified p-phenylene compd. into a charge transfer layer.
CONSTITUTION: The electrophotographic sensitive body is constituted of a charge transfer layer consisting of a layer of a high molecular linear compd. contg. p-phenylene residues and a group IIb element in the p-position of the p-phenylene compd. Suitable group IIb element is at least one among S, Se, Te, having ≥280°C m.p. Thus, an electrophotographic sensitive body having high sensitivity and low residual potential is obtd. Moreover, the film of the charge transfer layer is attained by the melt-sticking, coating, or vapor-deposition of the polymer, so an inexpensive electrophotographic sensitive body having high stability and high printing resistance is obtd.
