A printer comprises a recording portion with a thermal recording head for recording on a surface of a recording medium and a first conveying mechanism that conveys the recording medium. A thermal activation portion has a thermal activation head for heating another surface of the recording medium and a second conveying mechanism for conveying the recording medium. First and second discharge ports are disposed on a downstream side of the first and second conveying mechanisms, respectively. A pair of conveying rollers is arranged between the recording portion and the first discharge port and between the first discharge port and the thermal activation portion. The conveying rollers convey the recording medium from the recording portion to the first discharge port through normal rotation of the conveying rollers, change a conveyance course of the recording medium conveyed from the recording portion, and convey the recording medium to the thermal activation portion through reverse rotation of the conveying rollers.
