Abstract
An image forming apparatus includes a temperature sensor detecting an operating ambient temperature of the polygon motor, and a controller controlling the polygon motor and the paper feed mechanism. If the temperature detected by the temperature sensor is equal to or greater than a preset temperature, the controller controls, before operation for giving a command to start image formation is performed, the polygon motor to rotate; increases, in response to the operation, a rotational speed of the polygon motor up to a rated speed; and controls the paper feed mechanism to start conveying a sheet of paper at a time when a period of time variable depending on the detected temperature has elapsed, the period of time being preset to be shorter as the detected temperature increases, in expectation of a time required for the rotational speed of the polygon motor to reach the rated speed.
