An electrophotographic photosensitive member includes a charge transport layer containing (α) a charge transporting compound, (β) a binding resin in a proportion in the range of 50% by mass to 200% by mass relative to the mass of the charge transporting compound, (γ) a compound being at least one of xylene and toluene with a content in the range of 0.01% by mass to 2.00% by mass relative to the total mass of the charge transport layer, and (δ) a cycloalkanone with a content in the range of 0.01% by mass to 1.20% by mass relative to the total mass of the charge transport layer.
摘要:
The presently disclosed embodiments relate in general to flexible electrophotographic imaging members, such as layered photoreceptor structural simplification, and material reformulation for making and using the same. More particularly, the embodiments pertain to the incorporation of a plasticizer or mixture of plasticizers into the charge transport layer for rendering flatness such that an anticurl back coating is no longer needed to counteract and control the layered photoreceptor curling.
