PROBLEM TO BE SOLVED: To reliably prevent leakage of developer.SOLUTION: A developing device includes: a first sealing member that includes a roller part, a roller member that includes a shaft part protruding from an end of the roller part, and a hole part into which the shaft part is inserted, and is disposed to be opposite to the end of the roller part; a second sealing member that includes a hole part into which the shaft part is inserted, and is disposed to be in contact with a surface opposite to the roller member of the first sealing member; and a holding part that includes a step part holding the second sealing member, and an abutting part coming into contact with the first sealing member. The step part includes: a first regulation part that regulates the hole part into which the shaft part is inserted and movement of the second sealing member related to the axial direction of the shaft part; and a second regulation part that regulates the second sealing member related to the circumferential direction of the shaft part. The second sealing member has dimensions related to the shaft direction of the shaft part larger than the dimensions of the step part related to the shaft direction of the shaft part, and is assembled by being compressed in the step part. |
