Abstract
Provided is an electrophotographic photoreceptor capable of reducing the rotational torque of the photoreceptor and also reducing the increase in the rotational torque during long-term use when a cured layer obtained by curing a charge transporting compound having a radically polymerizable group is used as a protective layer. In the electrophotographic photoreceptor, a conductive support, a photosensitive layer, and a protective layer are laminated in this order. The protective layer is formed of a cured product of a composition containing the following: a charge transporting compound having a radically polymerizable functional group; and metal oxide particles surface-treated with a surface treating agent having a silicone chain in a side chain thereof.
