Abstract
An image forming apparatus includes a recording head to discharge ink to a recording medium to form an image thereon, an optical sensor to output a signal in response to intensity of reflection of light emitted to the direction of discharging the ink, a carriage that carries the recording head and the optical sensor, and a control unit to detect the position of the recording medium based on the signal output by the optical sensor and control the recording head to discharge the ink only onto the position of the recording medium, wherein the control unit acquires a value according to the signal output by the optical sensor in response to the movement of the carriage and detects the position of the recording medium when a predetermined relation between the value and a threshold continues at least for a predetermined interval in the movement of the carriage.
