Abstract
An electrophotographic photosensitive member includes a support, an undercoat layer formed on the support, and a photosensitive layer formed on the undercoat layer. The undercoat layer is an electron transporting layer and contains a metal salt of organic acid having at least one metal element selected from Fe, Co, Ni, Cu, and Zn.
Claims15
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 is an electron transporting layer,
- the undercoat layer comprises a metal salt of organic acid having at least one metal element selected from the group consisting of Fe, Co, Ni, Cu, and Zn, and
- (i) the undercoat layer is obtained by curing an electron transporting compound having a polymerizable functional group, or a composition containing an electron transporting compound having a polymerizable functional group, or
- (ii) the undercoat layer further comprises an electron transporting compound.
