Abstract
An electrophotographic photoreceptor characterized in comprising a resin layer containing a hardenable siloxane-based resin having a partial structure described below: ##STR1## wherein X represents a charge transportability providing group, which is a group bonding to Y in the formula via a carbon atom constituting said providing group, and Y represents at least a bivalent atom or group, excluding adjacent bonding atoms.
Claims41
An electrophotographic photoreceptor comprising a support, a photosensitive layer, and a resin layer obtained by hardening a siloxane resin compound containing a unit represented by formula (1), ##STR25## wherein X is a charge transportability providing group which bonds to Y via a carbon atom which is contained in said providing group, Y represents an at least two valent substituent other than silicon and carbon atoms, and wherein said siloxane resin compound is three-dimensionally cross-linked.
An electrophotographic photoreceptor comprising a support, photosensitive layer, and a resin layer obtained by hardening a siloxane resin compound by three dimensionally cross-linking by a reaction of an organic silicon compound, having a hydroxyl group or a hydrolizable group, with a charge transport compound having a hydroxyl group.
An electrophotographic photoreceptor comprising a support, photosensitive layer, and a resin layer obtained by hardening a siloxane resin compound by three dimensionally cross-linking by reacting an organic silicon compound, having a hydroxyl group or a hydrolizable group, with a charge transport compound having an amino group.
An electrophotographic photoreceptor comprising a support, photosensitive layer, and a resin layer obtained by hardening a siloxane resin compound by three-dimensionally cross-linking by reacting an organic silicon compound, having a hydroxyl group or a hydrolizable group, with a charge transport compound having a mercapto group.
A method of production of an electrophotographic photoreceptor having a support, a photosensitive layer and a resin layer, comprising
- (a) coating said support with said resin layer comprising a hardenable siloxane resin prepared by reacting an organic silicone, having a hydroxyl group or a hydrolizable group, with a charge transport compound having a hydroxyl group;
- and
- (b) heating to harden said resin layer by three-dimensionally cross-linking at a temperature above 50.degree. C.
