摘要： PROBLEM TO BE SOLVED: To provide a developing device that is supplied with developer by a developer supply device, and can prevent developer from scattering from a part where the developing device is connected with the developer supply device, and to provide a process cartridge and an image forming apparatus that have the developing device. SOLUTION: The developing device 5 is installed in the image forming apparatus, and thereby connects to a toner supply device serving as the developer supply device and is supplied with toner by the toner supply device. The developing device 5 is formed separately from the upper casing and a lower casing 50, which are developing casing forming the main body of the developing device 5. The developing device 5 has a developer receiving member 60 connecting to the toner supply device. The developer receiving member 60 is attached to the lower casing 50 via a cushion member 63 serving as an elastic member. The developer receiving member 60 is displaced relative to the developing casing by deformation of the cushion member 63. Thus, the toner receiving port 61, which is a developer receiving port connecting to the toner supply port, can be displaced relative to the lower casing 50. COPYRIGHT: (C)2009,JPO&INPIT
