Patent ID: 8808951

Claim:
An electrophotographic photosensitive body comprising a conductive support having thereon a layer comprising at least two p-terphenyl compounds selected form the following compounds (1) to (5): and at least one polycarbonate resin represented by the following general formula (I): wherein R 1 and R 2 which may be the same or different represent a hydrogen atom, a substituted or unsubstituted alkyl group or a substituted or unsubstituted aryl group; R 1 and R 2 may be combined to form a ring; R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 and R 10 which may be the same or different represent a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group or a halogen atom, p and q represent a molar compositional fraction (q includes zero); a ratio of p and q has a relationship satisfying the formula 0≦q/p≦2; Z represents a substituted or unsubstituted alkylene group having from 1 to 5 carbon atoms, a substituted or unsubstituted 4,4′-biphenylene group or a divalent group represented by the following general formula (II): wherein R 11 and R 12 which may be the same or different represent a hydrogen atom, a substituted or unsubstituted alkyl group or a substituted or unsubstituted aryl group; R 11 and R 12 may be combined to form a ring; R 13 , R 14 , R 15 and R 16 which may be the same or different represent a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group or a halogen atom, and r is an integer of from 0 to 3, in a mass ratio of the p-terphenyl compounds to the polycarbonate resin within the range of 2:8 to 7:3, with the proviso that when only one kind of the polycarbonate resin is used, the case where the polycarbonate resin represented by the general formula (I) has a structure that R 1 and R 2 are a methyl group, R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 and R 10 are a hydrogen atom, and q is 0 is excluded.
