The present invention relates to an improvement of a photosensitive member having a photosensitive layer which contains a specific amino compound as a charge transporting material.

Photosensitive member having photosensitive layer which comprises amino

The present invention relates to a photosensitive member comprising a charge generating material, a charge transporting material, a binder resin and a specified electronattracting material, preferably further specified hindered phenol compound.

Photosensitive member comprising electronattracting compound and

A photosensitive member is disclosed, which comprises a photosensitive layer containing a fluorescent bleaching agent comprising a coumarin compound represented by the formula (I): ##STR1##

Photosensitive member containing specific coumarin fluorescent bleaching

This invention relates to a photosensitive member with a charge generating layer and a charge transporting layer laminated on an electrically conductive substrate, in which the charge transporting layer comprises a charge transporting material and an aniline derivative represented by the following general formula [I] below; ##STR1## in which R.sub.1 and R.sub.2 are respectively an alkyl group or an aralkyl group, each of which may have a substituent; R.sub.3 -R.sub.7 are respectively a hydrogen atom, an alkyl group, an alkoxy group, a hydroxy group, an aryl group, an aralkyl group or a halogen atom.

Photosensitive member comprising specific aniline derivative

The present invention relates to a photosensitive member containing a specific bisazo compound described by general structural formula[I] and formed on an electrically conductive substrate; ##STR1## Wherein X is a hydrogen atom, halogen atom, alkyl radical, alkoxi radical, nitro radical or cyano radical; A is a diatomic radical selected from among the following: ##STR2## B is a coupler described by formulae [II] through [VI]; ##STR3## R is a hydrogen atom, halogen atom, alkyl radical, alkoxi radical, nitro radical or cyano radical; and Y is an aromatic carbocyclic residue or aromatic heterocyclic residue, each of which may have a substituent; G is a carbamoyl radical or sulfamoyl radical and may have a substituent; R.sub.1 is a hydrogen atom, alkyl radical, amino radical or carbamoyl radical, each of which may have a substituent, a carboxyl radical or cyano radical; M is an aryl group which may have a substituent, which is improved in photosensitivity and dispersibility.
