    • A fixing apparatus includes a light irradiation unit and a reflector. The light irradiation unit irradiates a recording medium conveyed in a conveying direction with laser light along a first direction that is substantially perpendicular to the conveying direction. The reflector reflects first to fourth angular components of a part of the laser light reflected at an irradiation position at which the recording medium is irradiated, such that a first intersection point between the first and third angular components after the reflection and a second intersection point between the second and fourth angular components after the reflection as seen in a second direction that is substantially perpendicular to the conveying direction and the first direction are at different positions in a direction of displacement of the recording medium, the direction of displacement crossing the conveying direction. A developing agent on the recording medium is melted by the laser light.

    • According to an aspect of the invention, a fixing device includes a laser beam irradiation unit and a conveying unit. The laser beam irradiation unit includes a plurality of laser beam sources and emits a plurality of laser beams to a surface of a recording medium. The conveying unit conveys the recording medium and/or the laser beam irradiation unit so that irradiated regions irradiated with the laser beams are moved in a given direction. When the plurality of laser beams is emitted to a toner image to fix the toner image, the plurality of laser beams satisfies conditions (A) and (B). The condition (A) is that the plurality of laser beams has substantially the same beam power and substantially the same width. The condition (B) is that the plurality of laser beams is independently emitted to the toner image.
