摘要： An electrophotographic photoconductor (photoconductor) according to the embodiment includes a conductive support, a photosensitive layer, and a protective layer. The protective layer is composed of a cured product as one body obtained by a radical reaction of a composition containing a radical polymerizable monomer having a radical polymerizable functional group, a metal oxide fine particle having a radical polymerizable functional group, and camphorquinone or a derivative thereof. The photoconductor is installed in an image forming apparatus equipped with a cleaning device for removing transfer residual toner on the photoconductor, and the cleaning device includes an elastic cleaning member disposed so that it can come into contact with the surface of the photoconductor.
