PROBLEM TO BE SOLVED: To provide a drive transmission device capable of certainly receiving an attachable/detachable unit without breaking even if large inertial force is applied on a body side drive output shaft when the attachable/detachable unit is installed to an image forming device, and to provide inexpensively an image forming device using the drive transmission device.SOLUTION: A drive transmission device includes: a process cartridge 60 having a driven shaft; a body side drive output shaft 281 for transmitting driving force to the process cartridge; a development unit coupling 220 and a body side coupling 280 for coupling and separating the driven shaft and the output shaft; a rolling bearing 286 provided on the output shaft; and a drive side plate 11 including a drive side plate thrust stopper 20 for supporting the rolling bearing. The drive side plate thrust stopper has: a cylindrical portion 21 extending along at least a part of an outer periphery of the rolling bearing, and a bottom portion 22 continuing from the cylindrical portion, and receiving a bottom surface of the rolling bearing.SELECTED DRAWING: Figure 3 |
