Abstract

Provided is an electrophotographic apparatus that suppresses the occurrence of a pattern memory and enables stable image formation under a high-temperature and high-humidity environment. The electrophotographic apparatus includes: an electrophotographic photosensitive member; a charging unit; an image exposing unit; a developing unit including a toner; a transfer unit; a cleaning unit; and a fixing unit. The electrophotographic photosensitive member includes a monolayer-type photosensitive layer containing a binder resin, a charge-generating substance, a hole-transporting substance, an electron-transporting substance, and silicon atom-containing particles. The monolayer-type photosensitive layer is a surface layer of the electrophotographic photosensitive member. The charge-generating substance is one of metal-free phthalocyanine or oxytitanium phthalocyanine. The silicon atom-containing particles are one of silica particles or silicone resin particles. The toner includes toner particles each containing a polyester resin having a polyethylene terephthalate segment.
