A developing device includes a seal member adhered to a frame along an axial direction of a developing roller. The seal member seals between the frame and an outer peripheral surface of the developing roller. The frame has a seal supporting surface extending along the axial direction, on which the seal member is supported in a cantilevered fashion. The seal member includes a sheet-like member and an elastic adhesive member. One end portion of the sheet-like member is fixed to the seal supporting surface through the elastic adhesive member, and the other end portion is in contact with the outer peripheral surface of the developing roller. The elastic adhesive member has a first surface adhered to the sheet-like member and a second surface adhered to the seal supporting surface, and at least one slit is formed along the axial direction from the second surface toward the first surface. |
