PROBLEM TO BE SOLVED: To provide a process cartridge that a developer stirring means can be driven on an optimum condition by simple constitution. SOLUTION: This process cartridge is constituted in such a way it can be loaded and unloaded in/from an image forming device main body and provided with an electrophotographic photoreceptor, a process means having at least a developing means acting on the electrophotographic photoreceptor, the 1st and the 2nd rotatable toner stirring members (developer stirring means) 10b1 and 10b2 housed in a developing frame body housing the developing means in order to stir developer (toner) and a driving means driving the stirring members 10b1 and 10b2. Besides, it is provided with a humidity detection member (humidity detection means) 100a detecting humidity in the developing frame body and a stirring control mechanism (control means) 100 controlling the rotation of the stirring member 10b2 based on the humidity detected by the detection member 100a. |
