Abstract: An electrophotographic process comprising the steps of:(a) charging an electrophotographic photosensitive member comprising a conductive substrate and a photosensitive layer which includes a charge generation layer and a charge transport layer containing a charge-transporting material;(b) forming an image on the charged electrophotographic photosensitive member by exposing the charged photosensitive member to light substantially free of rays having the wavelength band which can be absorbed by the charge-transporting material contained in the charge transport layer; and(c) developing the image with a developer.

Abstract: An electrophotographic photosensitive member comprises a layer containing at least one azo pigment represented by the following formula (I): ##STR1## in the formula, Cp represents a coupler residue; A.sub.1 and A.sub.2 each represent a divalent organic residue; n represents 0 or 1; and when n is 0, A.sub.3 represents substituted or unsubstituted alkyl, substituted or unsubstituted aryl, or --(CH.dbd.CH).sub.l --R', wherein R' is a substituted or unsubstituted heterocyclic ring residue an l is 0, 1 or 2, and when n is 1, A.sub.3 represents a divalent organic residue.

Abstract: An electrophotographic photosensitive member is characterized by having a layer containing at least one hydrazone compound represented by the following formula [I] or [II]: ##STR1## wherein R.sub.11 and R.sub.12 represent hydrogen, halogen, substituted or unsubstituted alkyl, alkoxy, substituted or unsubstituted aryloxy, or substituted amino, provided that at least one of R.sub.11 and R.sub.12 is substituted amino or alkoxy; R.sub.13 and R.sub.14 represent substituted or unsubstituted alkyl or substituted or unsubstituted aryl, provided that at least one of R.sub.13 and R.sub.14 is substituted or unsubstituted aryl, or R.sub.13 and R.sub.14, together with the nitrogen atom which links them, represent a nitrogen-containing heterocyclic ring; R.sub.15, R.sub.16, R.sub.17, and R.sub.18 represent hydrogen, halogen, substituted or unsubstituted alkyl, alkoxy, substituted or unsubstituted aryloxy, or substituted amino; m and n represent 0 or 1; R.sub.21 and R.sub.
