PROBLEM TO BE SOLVED: To provide a developing device, etc. capable of preventing the leakage of a developer even when there is a change in the interval between a developer carrying roller and a portion to which a sealing member is fixed. SOLUTION: In order to cope with a change in the interval between a developer carrying roller for carrying a developer and a portion to which an energizing member is fixed for energizing a sealing member to the developer carrying roller, for preventing the leakage of a developer from between the developer carrying roller and a housing; the energizing force with which the energizing member energizes the sealing member is differentiated between a central portion in the axial direction and other portions of the energizing member.
