Image reading apparatus and image forming apparatus that achieve appropriate continuous reading and recording medium

Abstract

An image reading apparatus includes an image reading circuit, an instruction accepting circuit, a timer circuit, a standby time determining circuit, and a reading start timing control circuit. The instruction accepting circuit accepts an image reading instruction. The timer circuit sets a preliminary specified reference event as an origin. The timer circuit measures an elapsed time from the origin until the instruction accepting circuit accepts the image reading instruction. The standby time determining circuit determines a standby time based on the elapsed time measured by the timer circuit. The reading start timing control circuit causes the image reading circuit to start image reading of the document at an elapse of the standby time determined by the standby time determining circuit from the reference event when the reference event occurs after the standby time determining circuit determines the standby time.
