Abstract
An image forming apparatus including: a reading device; an operating portion; a light source; a rotary polygon mirror; a motor configured to rotate the rotary polygon mirror; and a motor control portion configured to start the motor to control the motor at a first rotation speed in response to a fact that a predetermined action is performed on one of the operating portion and the reading device in a stopped state of the rotary polygon mirror, and then to control the motor at a second rotation speed higher than the first rotation speed in response to an instruction to start image formation from the operating portion, the motor control portion being configured to control the motor at the second rotation speed, without controlling the motor at the first rotation speed, in response to a fact that the receiving portion receives image data before the motor reaches the first rotation speed.
