A light-emitting device includes: a first light-emitting unit that extends in one direction and that has a first emission surface that emits light located along the one direction; a second light-emitting unit that is located in the one direction with respect to the first light-emitting unit, that extends in the one direction, and that has a second emission surface that emits light located along the one direction; a cleaning unit that is capable of moving in the one direction and an opposite direction that is opposite to the one direction to clean the first emission surface; a transmission part that extends from the cleaning unit in the one direction and that transmits a moving force for moving the cleaning unit to the cleaning unit; and an extending part that extends from the transmission part in the one direction to elongate the transmission part. When the cleaning unit is positioned furthest in the opposite direction, an end of the extending part in the one direction is located further in the one direction than a midpoint between an end of the first light-emitting unit in the one direction and an end of the second light-emitting unit in the one direction.

A laser recording device of an embodiment is for a thermal recording medium in which at least one color development layer developing a color through heat and a protective layer protecting recorded information obtained through color development of the at least one color development layer are laminated, and has light transmission properties before recording. The laser recording device includes a recording head in which emitters emitting laser light from laser light sources are arranged, and a recording controller performing parallel processing of control for causing the laser light sources to emit light independently of each other and guiding the laser light from the emitters to the thermal recording medium.
