Abstract
An image forming apparatus includes: a driving roller that conveys a paper sheet; a detector that detects a desired point on the driving roller; and a hardware processor that: acquires a waveform signal indicating one of a change in an image forming position with respect to the paper sheet and a change in a sheet conveyance velocity; extracts a synchronous waveform signal from the waveform signal acquired by the hardware processor, the synchronous waveform signal being synchronized with one revolution of the driving roller, the one revolution being detected by the detector; and inputs a drive signal to a drive source of the driving roller, the drive signal being input to weaken an amplitude of the synchronous waveform signal extracted by the hardware processor.
