PROBLEM TO BE SOLVED: To suppress leakage of a laser beam in a fixing device that irradiates a recording medium with the laser beam to fix a toner to the recording medium.SOLUTION: A lens pad 90 collects a laser beam Bm emitted from a laser beam emitting device. An opposing roll 82 is provided at a position in contact with the lens pad 90 to convey a recording medium S entered between the opposing roll 82 and lens pad 90. The lens pad 90 has a first face on which a laser beam is made incident and a second face from which a laser beam is emitted, and collects the laser beam made incident on the first face and emits the laser beam from the second face. A part of the second face is covered by a coating material 98 that does not transmit a laser beam. On a cross section perpendicular to the rotational axis of the opposing roll 82, a contact surface between the opposing roll 82 and lens pad 90 includes at least a part of a surface covered by the coating material 98.SELECTED DRAWING: Figure 5 |
