Motor control apparatus, image forming apparatus, motor control method, and program for implementing the method

摘要

A motor control apparatus which is capable of controlling driving currents for stepping motors with efficiency. A feedback stepping motor drives sheet feed rollers located most upstream on a sheet conveying path out of a plurality of rollers. A normal stepping motor drives sheet feed rollers located downstream on the sheet conveying path out of the plurality of rollers. A maximum current value required by the feedback stepping motor when a sheet is conveyed is detected. A driving current value for the normal stepping motor is set to a value according to the maximum current value before the sheet enters the downstream sheet feed rollers after passing the upstream sheet feed rollers.
