PROBLEM TO BE SOLVED: To reduce a load in removing sheet members 51a and 51b from communication ports 107a and 107b.SOLUTION: Sheet members 51a and 51b are partially adhered to a partition wall 103 in larger areas than other parts in terms of a direction of removal by a take-up device 600. Thus, a load in removing the sheets in a part of the removal direction increases. A CPU controls a clutch switching between connection and disconnection of drive between a drive motor and a plurality of developing devices 100 so that parts in the removal direction of the plurality of sheet members 51a and 51b can be removed at different timings in the developing devices 100. Thus, the timings of a high load shift from each other in removing the sheet members 51a and 51b, so that the load can be reduced. |
