Abstract
A drive deviceincludes a planetary roller type power transmission unit, a temperature sensor, a delay time determination unit, and an image processing control unit. The planetary roller type power transmission unit includes a plurality of planetary rollers at least a part thereof made from an elastic material that is pressed against the periphery of a motorrotation shaft, a ring that contacts the plurality of planetary rollers, a carrier roller, and an output shaft. The temperature sensormeasures the temperature Te of or near the planetary roller. The delay time determination unitdetermines the delay time Td from the start up time of the motoruntil the start of the image forming process. The image processing control unitstarts the image forming process after the delay time Td has passed from the start up time of the motor
