Abstract: An image formation device includes a plurality of motors, an overcurrent detection portion, a load application portion, and a specification portion. The plurality of motors each include an output shaft. The overcurrent detection portion detects an overcurrent with respect to a resultant current including currents flowing through the plurality of motors. The load application portion applies, while the plurality of motors are being rotated, a load to the output shaft of at least some of the plurality of motors. The load applied by the load application portion is a load for causing fluctuation components that enables the currents of the plurality of motors to be distinguished from one another to be generated in the resultant current. The specification portion specifies, when the overcurrent is detected, a motor that is a cause of the overcurrent from among the plurality of motors based on the resultant current.
