Title: Electrophotographic sensitive body
Inventor: KIMURA MICHIO
IPC: G03G5/14
Filed: 1990-11-27
Abstract: PURPOSE:To reduce defects of a coating film due to an electrically conductive substrate and to always maintain satisfactory sensitivity by forming an underlayer between the substrate and a photosensitive layer with zinc oxide powder, tin oxide powder and binding resin and specifying the binding resin content of the underlayer. CONSTITUTION:An underlayer between an electrically conductive substrate and a photosensitive layer is formed with zinc oxide powder, tin oxide powder and binding resin and the binding resin content of the underlayer is regulated to 25-50 vol.%. Since the underlayer reduces defects of a coating film due to the defects of the substrate and contains zinc oxide powder and tin oxide powder, residual potential rises hardly and potential by electrification and sensitivity hardly undergo a change even in the case of a thickened film. Dependency on environment is small because of the 25-50 vol.% binding resin content of the underlayer. The pref. thickness of the underlayer is 2-30 mum and the pref. amt. of the tin oxide is 4-25 vol.% of the total amt. of all the pigments in the underlayer. Defects of a coating film due to the substrate are reduced and satisfactory sensitivity can always be maintained.
