Abstract
(EN)
A method of image forming including an electrification step, an exposure step, a development step and a transfer step. In the method, use is made of a toner containing toner particles, the toner particles containing a binder resin and a colorant, and inorganic micropowder, and use is made of a photoreceptor provided at its surface with multiple mutually independent concave portions. The average short-axis diameter of openings of the concave portions, Lpc, satisfies the relationship Dg<Lpc<Dt (Dt is the weight average particle diameter of the toner, and Dg is the maximum number average particle diameter among the respective number average particle diameters of one or two or more inorganic microparticles constructing the inorganic micropowder), and the average circularity of the toner is in the range of 0.925 to 0.995.
