Abstract
A image forming apparatus includes: a motor; a mounting unit for receiving a cartridge including a detection target moved by a rotational driving force of the motor; a printing unit; a detecting unit for detecting the detection target at a detection position on a movement trajectory of the detection target; and a control unit for controlling the motor and the detecting unit. The control unit performs: a rotation control process of: accelerating the motor; rotating the motor at a constant speed in a time period when accelerating a rotational speed of the motor up to a target speed; detecting the detection target by the detecting unit while the motor rotates at the constant speed; and accelerating again the motor after completing the detection; and a determining process of determining a kind and/or a state of the cartridge on the basis of the detection result of the detecting unit.
