Summary:To provide an image forming apparatus that can suppress scattering of toner, while improving low-temperature fixability, a process cartridge, and a cartridge set.SOLUTION: There is provided an image forming apparatus that has an electrophotographic photoreceptor, and a developing device that has toner and is to supply the toner onto the electrophotographic photoreceptor. The electrophotographic photoreceptor has a surface layer that contains a binder resin (A). The binder resin (A) has a predetermined structure. The toner has toner particles. The toner particles contain a binder resin (B) and wax. The wax contains a predetermined diester compound. Also provided are a process cartridge, and a cartridge set.SELECTED DRAWING: Figure 1 【課題】低温定着性を改善しつつ、トナー飛び散りを抑制できる画像形成装置、プロセスカートリッジ及びカートリッジセットを提供する。【解決手段】電子写真感光体と、トナーを有し、電子写真感光体上にトナーを供給するための現像装置と、を有する画像形成装置であって、電子写真感光体が、結着樹脂（Ａ）を含有する表面層を有し、結着樹脂（Ａ）が所定の構造を有し、トナーがトナー粒子を有し、トナー粒子が結着樹脂（Ｂ）及びワックスを含有し、ワックスが所定のジエステル化合物を含有する、画像形成装置、並びに、プロセスカートリッジ及びカートリッジセット。【選択図】図１
