IMAGE FORMING SYSTEM AND IMAGE FORMING METHOD

To provide an image forming system and an image forming method that achieve both prevention of abrasion of an organic photoreceptor and reduction of attachment on the organic photoreceptor.SOLUTION: An image forming system of the present invention uses an organic photoreceptor, and a toner for electrostatic charge image development including toner particles. The organic photoreceptor has a protective layer containing curable resin. The toner particle has a shape in which at least one type of lubricant particles and at least one type of non-lubricant particles are contained in or attached onto surfaces of a plurality of convex parts or a surface between the plurality of convex parts on a toner base particle having the plurality of convex parts on the surface. An average interval D1 between the convex parts on the surfaces of the toner base particles, a median diameter D2 of the lubricant particle having the smallest median diameter, and a median diameter D3 of the non-lubricant particle having the largest median diameter satisfy the following formula (1). Formula (1) D3≤D1≤D2.SELECTED DRAWING: None 【課題】有機感光体の減耗抑制と有機感光体上付着物の低減とを両立する画像形成システム及び画像形成方法を提供することである。【解決手段】本発明の画像形成システムは、有機感光体と、トナー粒子を含む静電荷像現像用トナーとを用いた画像形成システムであって、前記有機感光体が、硬化樹脂を含有する保護層を有し、前記トナー粒子が、表面に複数の凸部を有するトナー母体粒子の前記複数の凸部表面上又は複数の凸部の間の表面上に、少なくとも一種の滑剤粒子と、少なくとも一種の非滑剤粒子とを含有又は付着させた形状を有し、前記トナー母体粒子表面における前記凸部の平均間隔Ｄ１と、メジアン径が最も小さい前記滑剤粒子のメジアン径Ｄ２と、メジアン径が最も大きい前記非滑剤粒子のメジアン径Ｄ３とが、下記式（１）の関係を満たすことを特徴とする。式（１） Ｄ３≦Ｄ１≦Ｄ２【選択図】なし
