Abstract
A developing device is provided. The developing device includes a housing, a developing agent carrier, and a developing agent leakage prevention member. The developing agent leakage prevention member has a first layer that is configured to contact an outer circumferential surface of a longitudinal end of the developing agent carrier; a second layer that is superimposed on the first layer and is configured to contact a portion of the housing; and an adhesive layer that is interposed between the first layer and the second layer, the adhesive layer partially bonding a first opposing surface of the first layer opposing the second layer to a second opposing surface of the second layer opposing the first layer such that an unbonded area where the first opposing surface and the second opposing surface are not bonded together is produced.
