The invention relates to a drive device, a robot, and an image forming apparatus, which can improve the wear resistance and strength of a gear close to an output shaft on a drive transmission system path. A drive device in which the same output shaft (2) is rotated by two motors (9A, 9B), while sharing the external gear (5) and the carrier (2), two planetary gear mechanisms are configured so thatthe planetary gears (3A, 3B) and the sun gears (4A, 4B) are exclusively used, and drive is transmitted from the two electric motors (9A, 9B) to the respective sun gears (4A, 4B). A control mechanism (11) capable of reducing backlash is provided by two motors (9A, 9B). A brake capable of switching between operation and non-operation may also be provided in the drive transmission path up to the planetary gears (3A, 3B) corresponding to the respective motors (9A, 9B). 本发明涉及驱动装置、机器人及图像形成装置，能够在驱动传递系统路径上提高与输出轴接近的齿轮的耐磨损性和强度。在通过两个电动机(9A)、(9B)使同一输出轴(2)旋转的驱动装置中，在共用外齿轮(5)和行星架(2)的同时，以行星齿轮(3A)、(3B)和太阳齿轮(4A)、(4B)为专用的方式构成两个行星式行星齿轮机构
