Patent ID: 8269435

Claim:
An image forming apparatus comprising: a conveying part configured to convey, during an image forming process, transfer paper or a toner image; and a motor control unit which controls rotation speed of a motor which drives the conveying part, wherein the motor control unit is configured to carry out control of rotation speed of the motor based on a rotation output signal output according to rotation of the motor, and the motor control unit includes: a storing part configured to store time information indicating time required for reflecting a speed control indicating value on rotation speed of the motor, the speed control indicating value being read by a motor driving part and then, being reflected on rotation speed of the motor by the motor driving part; a rotation speed information generating part configured to generate rotation speed information based on reception of the rotation output signal; a speed control indicating value generating part configured to generate the speed control indicating value based on the time information and the rotation speed information; and the motor driving part configured to read the speed control indicating value at a period which is based on the time information, and drive the motor based on the speed control indicating value.
