IMAGE FORMING SYSTEM AND METHOD FOR FORMING IMAGE

An image forming system uses: an organic photoreceptor; and a toner for electrostatic charge image development containing toner particles, wherein the organic photoreceptor has a protective layer containing a cured resin; the toner particle has a form in which at least one type of lubricant particle and at least one type of non-lubricant particle are contained or adhered on a surface of a plurality of convex portions or on a surface between the plurality of convex portions, of a toner base particle having the plurality of convex portions thereon; and an average spacing D1 of the convex portions on the surface of the toner base particle, 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 relationship of the following formula (1): Formula (1) D3≤D1≤D2.
