In at least one of the period when the conveying speed of a continuous record medium is accelerated until the conveying speed reaches a constant speed and the period when the conveying speed is decelerated to stop conveying the continuous record medium, a test pattern is recorded on the continuous record medium by a first image recording unit and a second image recording unit. The pattern is read by a first detection unit and a second detection unit, and a record check unit determines whether or not there is a record error in the test pattern.
