ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER, PROCESS CARTRIDGE, ELECTROPHOTOGRAPHIC APPARATUS, CHARGE TRANSPORT LAYER FORMING COATING LIQUID, AND METHOD FOR MANUFACTURING ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER

摘要

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. Also, a charge transport layer forming coating liquid contains (α′) a charge transport material, (β′) at least one selected from the group consisting of polycarbonate resins and polyester resins, (γ′) at least one of xylene and toluene, and (δ′) cyclopentanone. The proportion of (δ′) is in the range of 50% by mass to 85% by mass relative to the total mass of (γ′) and (δ′).
