FIXING DEVICE AND IMAGE FORMING APPARATUS

A fixing device includes a light source that emits laser light; a condensing member including a lens having a first surface from which the laser light enters and a second surface from which the laser light emerges, the lens condensing the laser light that has entered from the first surface and emitting the laser light from the second surface; and a roller provided in contact with the condensing member and that transports a recording medium advanced into a position between the roller and the condensing member. A portion of the second surface is made of a material that blocks the laser light. In a section perpendicular to an axis of rotation of the roller, a plane of contact between the roller and the condensing member includes at least a part of the portion made of the material that blocks the laser light.
