PROBLEM TO BE SOLVED: To provide an image forming apparatus with a developing apparatus, capable of preventing an increase in the rotating torque of a toner supply roller by decreasing a frictional resistance while effectively preventing a toner leakage between the toner supply roller disposed in the developing apparatus and a sealing member in contact with each end of the toner supply roller. SOLUTION: A washer 40, into which the roller shaft 20A of a toner supply roller 20 is fittingly inserted, is disposed in a place where a side sealing member 38 made of sponge and the end of a roller shaft 20B and the end of a roller 20C made of sponge are in contact with each other. The washer 40 is formed of a PET film sheet, and the end faces of the roller shaft 20B and a roller 20C of the toner supply roller 20 are brought into contact with the washer 40 that is in particular satisfactory in side characteristic. |
