Abstract
An image forming apparatus includes an oscillator configured to oscillate a laser beam, an irradiation portion configured to radiate the laser beam oscillated by the oscillator to an outside, a light absorption unit configured to absorb the laser beam and to convert the laser beam to heat, and a control unit. The control unit is configured to control, in an irradiation state, the irradiation portion to press the irradiation portion against a workpiece with first pressing force via the light absorption unit and irradiate the workpiece with the laser beam. The control unit is configured to control, in a non-irradiation state, the radiation portion to press the irradiation portion against the workpiece with second pressing force smaller than the first pressing force via the light absorption unit, or to separate the irradiation portion from the light absorption unit so as to set the second pressing force to zero.
