PURPOSE:To prevent the generation of a black streak at the time of transferring an image caused by vertical streaky melt-sticking onto a toner holding rotary body and moreover, reduction in the black density of the transferred image and the generation of fogging as much as possible by preventing toner from being flocculated at the time of supplying the toner, as much as possible. CONSTITUTION:In this developing device supplying the toner 33 in a toner container 31 from a toner supplying roller 35 to a developing roller 36, tuning the toner thereon into a thin layer by a toner layer thickness regulating member 37 and sticking the toner to an electrostatic latent image forming part, to attain development, a plate-like toner supply regulating member 40 having almost the same width as that of the toner supplying roller 35 is arranged in a contact state in the upper part of the roller 35, a gap A for regulating the quantity of the toner supplied to the contact part of the toner supplying roller 35 with the developing roller 36 from the toner container is provided on one end side of the toner supply regulating member 40 and the other end side is extended up to the inwall of the rear part of the toner container 31, to block the returning of the toner thereinto from the toner supplying roller 35. |
