Abstract: In the case where development is performed by a two-component developing method, a previous charge removal light-emitting portion applies charge removal light to a first charge removal target region of an effective outer circumferential surface of a photosensitive member on which effective outer circumferential surface an electrostatic latent image can be formed. The first charge removal target region includes a part of a magnetic brush contact region of the effective outer circumferential surface and a region of the effective outer circumferential surface between the magnetic brush contact region and a transfer position of a toner image.

Abstract: A developing device includes a supplying chamber, an agitating member, a toner carrier, a retaining part and a detecting part. The supplying chamber accommodates a toner replenished from a toner container. The agitating member agitates the toner in the supplying chamber. The toner carrier supplies an electrostatic latent image formed on an image carrier with the toner from the supplying chamber. The retaining part recovers and retains the toner dispersed in the vicinity of the image carrier and the toner carrier. The detecting part detects an amount of the toner in the retaining part. The retaining part is moreover configured to replenish the recovered toner from the retaining part to the supplying chamber when the detecting part detects an amount of the toner in the retaining part more than a predetermined amount in a state where the toner is needed to be replenished to the supplying chamber.

Abstract: A developing device of the present disclosure includes a developing roller, a toner supplying roller, a regulation blade, a casing, a toner receiver support member, a toner receiver member, and a vibration generator. The toner receiver support member is disposed inside the casing so as to face the developing roller or the toner supplying roller between the regulation blade and an image carrier. The toner receiver member is disposed along a longitudinal direction of the toner receiver support member, and has a toner receiving surface that receives toner falling from the developing roller. The vibration generator vibrates the toner receiver member. At each end part of the toner receiving surface in its longitudinal direction, there is formed a thin-walled portion that is thinner in thickness than other parts of the toner receiving surface.

Abstract: A developing device includes a developing roller, a toner supplying roller, a regulation blade, a casing, a toner receiver support member, a toner receiver member, and a vibration generator. The toner receiver member is disposed along a longitudinal direction of the toner receiver support member facing the developing roller, and has a toner receiving surface inclined downward from the image-carrier side toward the toner-supplying-roller side. The toner receiving surface is disposed to be inclined so as to rise from the toner-supplying-roller side toward the image-carrier side. The toner receiving surface has a plurality of grooves formed therein to be inclined to approach a center part of the toner receiving surface from each end side of the toner receiving surface in its longitudinal direction, from an edge of the toner receiving surface on the image-carrier side toward an edge of the toner receiving surface on the toner-supplying-roller side.
