A member to be coated is placed in a hollow portion of an external member and a coating material is charged in a gap between the member to be coated and the external member. The member to be coated has another member fixed thereto. The member to be coated is drawn from the hollow portion of the external member to form a coated film thereon.

Process for producing a coating of uniform thickness of an element

This invention is directed to photosensitive material for electrophotography and more particularly it is directed to the improvement of the properties with respect to humidity of photosensitive material by using photoconductive material in combination with ion exchange resin or by using photoconductive material which is previously washed in an aqueous solution in the presence of ion exchange resin.

Photosensitive element for electrophotography

An electrophotographic photosensitive medium comprises a photoconductive insulating binder layer and a clearcoling layer formed by applying a dispersion of an organic high polymer on the photoconductive insulating binder layer.

Electrophotographic photosensitive media

An electrophotographic photosensitive member comprises a photoconductive insulating binder layer and a clearcoling layer overlying said photoconductive insulating binder layer and essentially consisting of a resin having an acid group in the molecule. The clearcoling layer may be produced by applying an aqueous coating material composed of a resin having a neutralized acid group and then drying.

Electrophotographic photosensitive media and process for manufacturing

Method of removing surface ionic impurities on inorganic photoconductive

An electrophotographic photosensitive member is produced by a method in which a photoconductive layer is provided on a base, a polymeric solventless-type liquid resin adhesive is placed between said photoconductive layer and an overlying insulating layer and, by applying pressure on said insulating layer to spread said resin, said insulating layer is secured closely to the photoconductive layer through said adhesive layer. Fine grains of photoconductive material may be dispersed in said adhesive to provide a second photoconductive layer.
