Method for producing electrophotographic photosensitive member

A method for producing an electrophotographic photosensitive member comprising a support, a charge generating layer formed on the support, and a charge transporting layer formed on the charge generating layer, the method comprising:

• forming a coat for the charge transporting layer using a charge-transporting-layer coating liquid, and
• drying the coat to form the charge transporting layer, wherein
• the charge transporting layer is a surface layer,
• the charge-transporting-layer coating liquid comprises:
• (α) a charge transporting substance;
• (β) at least one resin selected from the group consisting of
• a polycarbonate resin having a structural unit represented by the following formula (1A), and
• a polyester resin having a structural unit represented by the following formula (1B);
• (γ) an aromatic hydrocarbon solvent;
• and
• (δ) a compound having a boiling point under 1 atmosphere higher than that of the (γ);
• the charge-transporting-layer coating liquid is free of any polyester resins having a siloxane structure at the end thereof and any polycarbonate resins having a siloxane structure at the end thereof;
• and
• the (α), the (γ) and the (δ) satisfy the following expression:
• X(g)>Y(g)
• wherein,
• X(g) represents the solubility of the (α) in 100 g of the (γ) in an environment at 23° C. under 1 atmosphere, and
• Y(g) represents the solubility of the (α) in 100 g of the (δ) in an environment at 23° C. under 1 atmosphere;
• wherein,
• R1 to R4 each independently represent a hydrogen atom, a methyl group or a phenyl group,
• X1 represents a single bond, an oxygen atom, a cyclohexylidene group or a bivalent group represented by the following formula (A),
• R11 to R14 each independently represent a hydrogen atom, a methyl group or a phenyl group,
• X2 represents a single bond, an oxygen atom, a cyclohexylidene group or a bivalent group represented by the following formula (A), and
• Y1 represents a meta-phenylene group, a para-phenylene group, a cyclohexylene group or a bivalent group represented by the following formula (B):
• wherein,
• R21 and R22 each independently represent a hydrogen atom, a methyl group, an ethyl group or a phenyl group,
• R31 to R38 each independently represent a hydrogen atom, a methyl group or a phenyl group, and
• X3 represents a single bond, an oxygen atom, a sulfur atom or a methylene group.
