A recording section is configured to record an image on a recording medium. An endless conveying belt has a surface disposed in confrontation with the recording section and is configured to move in a conveying direction with the recording medium supported by the surface, thereby conveying the recording medium in the conveying direction. A measuring section has a detecting region and configured to measure a position of the conveying belt with respect to a perpendicular direction that is perpendicular to the conveying direction. The measuring section includes an optical sensor that is configured to detect the position of the conveying belt with respect to the perpendicular direction. A sensor moving section is configured to move the sensor based on a measurement result of the measuring section, such that the conveying belt is detected in the detecting region.
