ABSTRACT:
A photosensitive member having stable electrophotographic characteristics can be constituted by an electroconductive support and a photosensitive layer disposed thereon and containing a novel fullerene compound having an organosilicon group as a charge-transporting substance. The fullerene compound may preferably have a polyhedral structure, particularly that of Buckminsterfullerene (C.sub.60) and be represented by the formula: C.sub.60 (A).sub.n . . . (2), wherein A denotes an organosilicon group represented by the formula: ##STR1## (wherein R.sub.1-1 and R.sub.1-2 independently denote a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted silyl group, a substituted or unsubstituted germyl group, a halogen atom, or a group constituting a substituted or unsubstituted ring by a mutual combination of R.sub.1-1 and R.sub.1-2 together with the Si atom in the formula); and n is an integer of 1 to 5, and a plurality of A in the case of n being two or larger can be the same or different with each other.
