摘要
An image forming unit (30') forms a black image. A motor (M1K; M2K) drives the image forming unit. A control circuit (207) controls the motor. A first connector (301a; 301c) to which the motor is connected via a control line. A second connector (301b; 301d) to which a control target is not connected. A substrate (200) on which the control circuit, the first connector, and the second connector are arranged. A predetermined mark (310b; 310d) is formed on the substrate through silk screen printing. A distance between the predetermined mark and the second connector is shorter than a distance between the predetermined mark and the first connector.
