PROBLEM TO BE SOLVED: To provide a developing device where sealing tape can be easily stripped off and extracted immediately before use even when the developing device is miniaturized. SOLUTION: In the device, a free end part 4a where the sealing tape 4 is not stuck on is pulled outside a housing from an opening 1a of the housing 1 and the sealing tape 4 is stripped and extracted by pulling the pulled out free end part 1a. Furthermore, the sealing tape 4 is pulled out in a state where it is in contact with a developer carrier (developing roll) 3. |
