PROBLEM TO BE SOLVED: To provide a developing device that prevents the occurrence of a failure in take-up of a sheet-like member even when taking up the sheet-like member in a direction intersecting with the width direction, a process cartridge, and an image forming apparatus.SOLUTION: A developing device includes a take-up shaft 13k that rotates in a predetermined direction to take up a sheet-like member 13m that has formed a closed space accommodating developer G inside a developing device 13, in a take-up direction that is a direction intersecting with the width direction of the sheet-like member 13m, so that the sheet-like member 13m is removed when the developing device is started to be used in an image forming apparatus body 1. A take-up path in the take-up direction where the sheet-like member 13m is taken up by the take-up shaft 13k is formed to be longer at the center part in the width direction than at both ends in the width direction.SELECTED DRAWING: Figure 5 |
