Abstract
A developer transport body transports a developer on a transport surface in a predetermined direction. This transport surface is composed of a first constituent surface which renders relatively large the absolute value of a charge amount of the developer due to friction, and a second constituent surface disposed in an area downstream of and adjacent to the first constituent surface and which renders the absolute value of the charge amount of the developer smaller than if the first constituent surface was disposed in the area. Therefore, when the developer is moved toward a latent-image forming surface by electrostatic force, the developer is less likely to be affected by disturbing forces other than the electrostatic force. Further, since the absolute value of the charge amount of the developer becomes smaller on the second constituent surface, adhesion of the developer to the transport surface and aggregation of the developer can be restrained.
