Abstract
The present invention provides a laminated-type photosensitive member having a photosensitive layer comprising; a charge generating layer and a charge transporting layer having a layer thickness of 25 .mu.m or more and containing an arylamine compound as a charge transporting material and an electron-accepting compound having an electron; affinity of 0.85-1.0 eV on an electrically substrate.
Claims8
A laminated-type photosensitive member having a photosensitive layer comprising;
- a charge generating layer and
- a charge transporting layer of 25 .mu.m or more thickness containing a binder resin, an arylamine compound as a charge transporting material of 0.2-2 parts by weight on the basis of one part by weight of the binder resin, and an electron-accepting compound of 1-10 percent by weight to the charge transporting material, said electron accepting compound having an electron affinity of 0.85-1.0 eV,
- on an electrically conductive substrate.
A photosensitive member of claim 1, in which the arylamine compound is represented by the following general formula [III];
- ##STR14## in which Ar-Ar.sub.4 and X are the same as those in the formula [I] of claim 14;
- R.sub.4 -R.sub.6 are respectively a hydrogen atom, an alkyl group, an alkoxy group or a halogen atom.
A laminated-type photosensitive member which is installed in a copying system working at a circumferential speed of the surface of the photosensitive member of 250 mm/sec or more, in which a photosensitive layer comprises;
- a charge generating layer and
- a charge transporting layer of 25 .mu.m or more thickness containing a binder resin, an arylamine compound as a charge transporting material of 0.2-2 parts by weight on the basis of one part by weight of the binder resin, and an electron-accepting compound of 1-10 percent by weight to the charge transporting material, said electron accepting compound having an electron affinity of 0.85-1.0 eV,
- on an electrically conductive substrate.
