Patent ID: 7499654

Claim:
An image recording apparatus including a transport path of a recording material, and an image recording unit in the transport path which records an image in the recording material during transportation of the recording material in the transport path, the image recording apparatus comprising: a recording material detection unit which is provided in the transport path and which detects at least one edge at a side end of the recording material transported in the transport path; an operation mode determination unit discriminating whether an incorrect detection can be performed in detecting the edge by the recording material detection unit, and determining an operation mode based on a discrimination result; and a control unit which controls the image recording unit to perform an image recording process on the recording material in the operation mode, wherein when the operation mode determination unit discriminates that the incorrect detection can be performed only on detection of a first edge of the recording material, the operation mode determination unit determines an operation mode of performing the image recording process using a detection result on a second edge.
