Abstract: An image forming apparatus configured to scan laser light on a photoconductive body with a polygon mirror rotated by a polygon mirror motor includes a first determining unit, a second determining unit, and a storage unit. After the polygon mirror motor is started and shifts to steady rotation in a target rotating speed range, the first determining unit determines, repeatedly at a regular interval, whether rotating speed of the polygon mirror motor is within the target rotating speed range. If the rotating speed is outside the target rotating speed range a specified continuous number of times, the second determining unit determines that failure of the polygon mirror motor occurred. If the rotating speed returns from the outside to within the target rotating speed range a number of times less than the specified continuous number of times, the storage unit stores the number of times.

Abstract: An image forming apparatus includes a polygon mirror configured to deflect a laser beam toward a photoconductor and a polygon mirror motor configured to rotate the polygon mirror. A controller acquires a measurement of a spin up time taken for a rotation speed of the polygon mirror motor to reach a target rotation speed range. The controller determines whether the spin up time is between (a) a first threshold time predefined based on a period of time required for the rotation speed of the polygon mirror motor to reach the target rotation speed range and (b) a second threshold time predefined as a period of time indicating that the polygon mirror motor is broken. The controller stores history data regarding the spin up time in response to a determination that the spin up time is between the first threshold time and the second threshold time.
