Image forming apparatus and image forming method
10960683 · 2021-03-30 · ·

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.

Thermal transfer light pen and thermal transfer apparatus

A thermal transfer light pen and a thermal transfer apparatus favorably perform thermal transfer even using light as a heat source to a thermal transfer sheet and performing thermal transfer to a transfer object with an uneven surface. A thermal transfer light pen includes a hollow pen body including a front end portion, a pressing body in the front end portion of the pen body and including a curved surface projecting toward a front end, a light guide including a first end and a second end, at least a portion of the light guide inside the pen body, and a light source connected to the first end of the light guide. The second end of the light guide is disposed in the front end portion of the pen body and faces the pressing body in the pen body. The pressing body is made of a material transparent to light emitted from the light source.
