    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.

    Abstract: A developing device includes a toner carrying member, a developer carrying member, a layer thickness restricting portion, a rotation control portion, and a developer carrying member difference voltage control portion. The rotation control portion, when developing is not performed, causes the developer carrying member to rotate forwardly and then to rotate reversely. The developer carrying member difference voltage control portion, in the non-developing forward rotation state, sets a voltage of the developer carrying member that is based on a potential of the toner carrying member, to a voltage that is smaller than a first reference voltage that is set when the developing is performed. The non-developing forward rotation state is a state in which the developer carrying member rotates forwardly when the developing is not performed.

    Abstract translation: 显影装置包括调色剂承载构件,显影剂承载构件,层厚度限制部分,旋转控制部分和显影剂承载构件差异电压控制部分。 旋转控制部在不进行显影时,使显影剂承载构件向前旋转,然后反转。 显影剂承载构件差动电压控制部分处于非显影正向旋转状态,将基于调色剂承载构件的电位的显影剂承载构件的电压设定为小于第一参考电压的电压, 在显影时进行设定。 非显影正向旋转状态是当不进行显影时,显影剂承载构件向前旋转的状态。
