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.
