Abstract
PURPOSE:To perform developing for a large number of times repeatedly, by performing the developing by specifying developing efficiency. CONSTITUTION:A developer layer consisting of a two component group developer including toner particle powder and carrier particle powder is formed on a developer carrier supporting body so that the developing efficiency (eta) shown in equation I can exceed 0.40. And an electrostatic latent image on a latent image supporting body is developed under a vibrating electric field by supplying the developing layer so as not to be brought into contact with the latent image supporting body to a developing area where the developer carrier supporting body is confronted with the latent image supporting body. In the equation I, (m) represents a toner sticking quantity (mg/cm<2>) on the electrostatic latent image, and also, a primary sticking quantity. And it is possible to set the developing efficiency (eta) at a value exceeding 0.40 by controlling a supplying toner quantity mg/cm<2> T to the developing area actually. In such a way, it is possible to suppress the generation of selective developing, and to perform the developing the superior developing for a large number of times repeatedly.
