Abstract:
1. An image forming apparatus that forms an image on a recording medium by conveying the recording medium in a direction orthogonal to a scanning direction of a carriage having a recording head, comprising: a first detecting unit mounted on the carriage and configured to detect a leading edge of the recording medium; a second detecting unit placed upstream from the first detecting unit in the direction that the recording medium is conveyed, and configured to detect the recording medium; and a control unit configured to control operations of the image forming apparatus based on a detection result from the first detecting unit or the second detecting unit, wherein the control unit determines based on the detection result from the second detecting unit a timing at which the recording medium is to reach a detection position where the first detecting unit detects the leading edge of the recording medium, and when the recording medium is to reach the detection position before the first detecting unit reaches the detection position, uses the detection result from the second detecting unit to perform an image forming process.
