PROBLEM TO BE SOLVED: To prevent a deterioration in parts made of urethane resin, caused by contact with toner, even if as the toner in a developer any kind of toner is used, by using ether urethane resin as the urethane resin to form the parts being in a contact with the developer. SOLUTION: In an image forming device, when the contact part with the developer 2 is made of the urethane resin, as this urethane resin the ether urethane resin is used. Further, in a developing device 20, a seal member for inhibiting the toner 2a in the developer 2 from being scattered outside from the developing device 20 is made of the ether urethane resin. Further, in a supplying member 30, the following members are made of the ether urethane resin; a supplying roller in a supplying part for supplying the toner 2a to the developing device 20, a seal member for suppressing the leakage of the toner 2a and a seal member for suppressing the leakage of the toner 2a in a measuring part having a measuring roller for measuring the quantity of the toner 2a supplied to the developing device 20. |
