Abstract: An image recording apparatus and an image recording method utilize a setting unit variably setting a length of time between an end of recording on a first recording side (surface) of a recording medium and a start of recording on a second recording side (reverse side) of the recording medium in accordance with image data for recording on the first recoding side of the recording medium.

Abstract: A recording apparatus includes a recording section, a convey section, and a discharge section. The invention further includes an urging device for urging a pinch roller against a recording sheet, an urging force controller for controlling an urging force of the urging device, and a detector for detecting that a trail end of the recording sheet is conveyed to a predetermined position disposed upstream of a position where the trail end of the recording sheet leaves the pinch roller. The urging force controller reduces or releases the urging force of the urging device on the basis of a detection result from the detector, thereby eliminating the force of the pinch roller acting on the trail end of the recording sheet. The apparatus prevents the conveying accuracy of the recording sheet from being adversely affected.
