ABSTRACT:
An electrophotographic photoreceptor comprising a support having provided thereon at least one photoconductive layer containing an inorganic photoconductive material and a binder resin is disclosed, wherein the binder resin comprises (A) at least one resin having a weight average molecular weight of from 1.times.10.sup.3 to 2.times.10.sup.4 and containing from 0.1 to 20% by weight of a copolymerizable component containing at least one acidic group selected from the group consisting of ##STR1## wherein R represents a hydrocarbon group or --OR'; and R' represents a hydrocarbon group, and a cyclic acid anhydride-containing group, and (B) at least one copolymer resin comprising a monofunctional macromonomer having a weight average molecular weight of 2.times.10.sup.4 or less, the macromonomer containing at least one polymerizable component represented by formula (B-2) or (B-3): ##STR2## wherein X.sub.0 represents --COO--, --OCO--, --CH.sub.2 OCO--, --CH.sub.2 COO--, --O--, --SO.sub.2 --, --CO--, ##STR3## wherein R.sub.1 represents a hydrogen atom or a hydrocarbon group; Q.sub.0 represents an aliphatic group having from 1 to 18 carbon atoms or an aromatic group having from 6 to 12 carbon atoms; b.sub.1 and b.sub.2, which may be the same or different, each represents a hydrogen atom, a halogen atom, a cyano group, a hydrocarbon group, --COO--Z or --COO--Z bonded via a hydrocarbon group, wherein Z represents a hydrogen atom or a substituted or unsubstituted hydrocarbon group; and Q represents ##STR4## wherein Y represents a hydrogen atom, a halogen atom, an alkoxyl group or --COOZ', wherein Z' represents an alkyl group, an aralkyl group or an aryl group, with a polymerizable double bond-containing group represented by formula (B-1): ##STR5## wherein V has the same meaning as X.sub.0 ; and a.sub.a and a.sub.2, which may be the same or different, each has the same meaning as b.sub.1 and b.sub.2, being bonded to only one of terminals of the main chain thereof, and a monomer represented by formula (B-4): ##STR6## wherein X.sub.1 has the same meaning as X.sub.0 ; Q.sub.1 has the same meaning as Q.sub.0 ; and c.sub.1 and c.sub.2, which may be the same or different, each has the same meaning as b.sub.1 and b.sub.2. The photoreceptor exhibits excellent electrostatic characteristics, image formation performance as well as printing properties, irrespective of change in environmental condition or the kind of sensitizing dyes to be used in combination.
