ABSTRACT:
A developing device includes a toner supplying roller, a developing roller for transferring the one-component toner to a developing position by performing a developing rotation in an image forming operation and moving away from the developing position, a sealing member arranged in a vicinity of the developing roller, and a toner layer regulating roller arranged in contact with the developing roller for locking a rotating operation in the image forming operation, for regulating the one-component toner which adheres on a surface of the developing roller into a thin layer and for freely following the developing roller in a non-image forming operation. A compulsory toner consumption operation is performed to supply toner onto the image bearing member after termination of the non-image forming operation.
