    摘要： An electrophotographic photoreceptor includes a cured outermost layer that includes a polymerized cured product including at least an inorganic filler and a phenol derivative. The inorganic filler is surface-modified with a surface modifier. The phenol derivative has a structure represented by Formula (1). In Formula (1), R1 and R3 each independently represent an alkyl group having three or more carbon atoms, R2 and R4 each independently represent a hydrogen atom or an alkyl group having 1 to 10 carbon atoms, and L1 represents a linking group having at least 10 atoms with an atomic number of 12 or more.

    摘要： Provide is an electrophotographic image forming method containing: a charging step, an exposure step, a developing step, a transfer step and a cleaning step by using a photoreceptor, wherein the charging step has a charging device for charging the surface of the photoreceptor; the photoreceptor has a protective layer, the protective layer contains a polymerized cured product of a composition containing a polymerizable monomer and an inorganic filler, a surface of the protective layer has a plurality of convex portions due to protrusion of the inorganic filler; in the developing step, a toner in which alumina particles are externally added to toner mother particles is used, and an average distance R between adjacent convex portions among the plurality of convex portions is set in the range of 100 to 250 nm.
