Abstract: An image holding member comprises a hollow cylindrical photosensitive member provided with a photosensitive layer on the surface of a hollow cylinder and a bonding member to be bonded to said photosensitive member at the end portion thereof, said bonding member being adhered to said photosensitive member with a non-solvent type adhesive to be made into an integrated structure.An image holding member comprises a hollow cylindrical photosensitive member having a photosensitive layer on the surface of a hollow cylinder provided with a projection at substantially the central portion of said cylinder on the bottom face closed at one end of said cylinder and a supporting member having a hole fittable with said projection at the central portion which is adhered to said photosensitive member with a non-solvent type adhesive to be made into an integrated structure.

Abstract: An electrophotographic photosensitive member having at least a substrate, a photosensitive layer, and an intermediate layer therebetween, characterized in that the intermediate layer is a hardened coating film formed from a liquid dispersion comprising(a) an electro-conductive powder and(b) a composition which contains either a resin or an oligomer and a crosslinking agent and is liquid at ordinary temperature in the absence of solvent.

Abstract: An electrophotographic photosensitive member has at least a charge generation layer and a charge transport layer. The charge transport layer comprises a charge transporting material and a resin which contains at least 95% by weight of components of molecular weight of 500 or higher.

Abstract: A coating device was provided for coating an object to be coated with a paint by dipping the object into a coating bath containing a paint, which comprises a member for uniformizing the flow of a paint gushing out from the lower part of the coating bath toward the upper part thereof, the member being provided in the coating bath at a lower part thereof. Coating was carried out with the coating device.

Abstract: In an electrophotographic photosensitive member having a charge generation layer and a charge transport layer formed by a dip-coating method, a length (H) expressed by the formula ##EQU1## of the charge generation layer is substantially the same as that of a film thickness changing portion of the charge transport layer (where V(t) represents an accelerating velocity from a velocity V1 to a velocity V2, and a substrate is pulled up at the velocity V1 until a time T1 has elapsed (t=T1) after the pulling up operation was started (t=0), is pulled up upon increasing the velocity from V1 to V2 until a time T2 has elapsed (t=T2) after the time T1, and thereafter is pulled up at the velocity V2 until a coating operation is completed after the time T2).

Abstract: An electrophotographic photosensitive member having a conductive substrate and a photosensitive laminate comprising a charge generation layer and a charge transport layer formed by dip coating, characterized in that the charge transport layer has a portion where the thickness increases gradually from the upper end of the layer and the charge generation layer has a portion formed, correspondingly to the increasing thickness portion of the charge transport layer, so as to increase the thickness gradually from the upper end of the layer.

Abstract: A coating method characterized in that an object of coating is dipped in a coating liquid so as to be positioned in the region surrounded by a helical agitator blade which is being revolved around the axis of the helix in the coating liquid to uniform the composition thereof.

Abstract: An electrophotographic photosensitive member characterized by having a phenolic resin layer formed from a resol coat, between a substrate and a photosensitive layer.

Abstract: An electrophotographic photosensitive member comprises a substrate and a photosensitive layer, and an electroconductive layer containing an electroconductive material, a binder and a leveling agent is provided between the substrate and the photosensitive layer. The silicone compound leveling agent improves the interfaces between the electroconductive layer and both the substrate and photosensitive layer.

Abstract: An electrophotographic photosensitive member provided with a novel intermediate layer between the substrate and the photosensitive layer. This intermediate layer is a resin layer in which an alumina- or tin oxide-treated titanium oxide powder is dispersed. The thickness of this intermediate layer is the second power or more of the maximum surface roughness of the substrate when the length is denoted in terms of a micron as a unit.

Abstract: Image-holding member for holding electrostatic images and/or toner images comprising an insulating layer composed of curable epoxyacrylate resin on the surface of the image-holding member.
