Abstract
A method of forming an image on a substrate with an electrophotographic photoreceptor and a toner, wherein the electrophotographic photoreceptor has an electroconductive substrate; the electroconductive substrate has a surface roughness Ra of from 0.01 μm to 0.3 μm; the toner contains toner matrix particles formed in an aqueous medium, has a volume median diameter (Dv50) of from 4.0 μm to 7.0 μm; and the relationship between the volume median diameter (Dv50) and the percentage in number (Dns) of toner particles having a particle diameter of from 2.00 μm to 3.56 μm satisfies: Dns≦0.233EXP(17.3/Dv50) (1) where Dv50 is the volume median diameter (μm) of the toner, and Dns is the percentage in number of toner particles having a particle diameter of from 2.00 μm to 3.56 μm.
