Claims20
An electrophotographic photosensitive member comprising:
- a support;
- an undercoat layer formed on the support;
- and
- a photosensitive layer formed on the undercoat layer,
- wherein the undercoat layer comprises:
- metal oxide particles whose surfaces have been treated with a silane coupling agent;
- a binder resin;
- and
- an organic acid metal salt having at least one metal element selected from the group consisting of bismuth, zinc, cobalt, iron, nickel, and copper.
A method of 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:
- metal oxide particles whose surfaces have been treated with a silane coupling agent,
- a blocked isocyanate compound,
- a polyol, and
- an organic acid metal salt having at least one metal element selected from the group consisting of bismuth, zinc, cobalt, iron, nickel, and copper;
- and
- forming a coating film of the coating liquid for an undercoat layer, and
- drying and curing the coating film to form the undercoat layer.
