Method for producing electrophotographic photosensitive member

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

• preparing a coating liquid for an undercoat layer containing:
• zinc oxide particles;
• a polyol;
• a blocked isocyanate compound whose isocyanate group is blocked with a structure represented by the following formula (1);
• and
• a solvent mixture;
• forming a coat of the coating liquid for an undercoat layer, and
• drying and curing the coat to form the undercoat layer,
• wherein, in the formula (1)
• X represents a single bond or an oxygen atom,
• R1 and R2 each independently represent an alkyl group having 1 to 4 carbon atoms, and
• wherein the solvent mixture comprises:
• a monohydric alcohol in an amount of 1 chemical equivalent or more based on the structure represented by the formula (1), and 90% by mass or less based on the total mass of the solvent mixture;
• and
• a ketonic solvent and/or a cyclic ether solvent in an amount of 7% by mass or more based on the total mass of the solvent mixture.
