Abstract
A flash fixing apparatus effectively collect vapor gas produced at the time of fixation while fixing a toner image of medium by means off flashlight. In the flash fixation unit, vapor gas produced in flash fixation flows toward the medium transportation direction. Utilizing this phenomenon, a gas suction face is provided in a gas collector so as to receive the vapor gas flowing toward the medium transportation direction. Otherwise, a gas blast portion is provided at the rear stage of the gas collector. The vapor gas flows to the gas suction face naturally, bringing about improved gas collection efficiency.
Claims16
A flash fixation apparatus for fixing a toner image on a medium under transportation by means of flash light comprising:
- a flash fixation unit for emitting said flashlight;
- a gas collector for collecting vapor gas produced in flash fixation, being disposed at the downstream side toward said medium transportation direction of said flash fixation unit;
- and
- a guide for altering said medium transportation direction, being disposed between said flash fixation unit and said gas collector,
- wherein said gas collector having a gas suction face disposed along said altered transportation direction.
A flash fixation apparatus for fixing a toner image on a medium under transportation by means of flash light comprising:
- a flash fixation unit for emitting said flashlight;
- a gas suction unit for sucking vapor gas produced in flash fixation, being disposed at the downstream side toward said medium transportation direction of said flash fixation unit;
- and
- a gas blast mechanism for blasting gas to said medium, being disposed at the downstream side of said gas suction unit.
A printer for forming a toner image onto a medium being transported at a predetermined transportation velocity comprising:
- an image forming unit for forming a toner image onto said medium;
- and
- a flash fixation device for fixing said toner image formed on said medium by means of flashlight,
- wherein said flash fixation device comprising:
- a flash fixation unit for emitting said flashlight;
- a gas collector for collecting vapor gas produced in flash fixation, being disposed at the downstream side toward said medium transportation direction of said flash fixation unit;
- and
- a guide for altering said medium transportation direction, being disposed between said flash fixation unit and said gas collector,
- and wherein said gas collector has a gas suction face disposed along said altered transportation direction.
A printer for forming a toner image onto a medium being transported at a predetermined transportation velocity comprising:
- an image forming unit for forming a toner image onto said medium;
- and
- a flash fixation device for fixing said toner image generated on said medium by means of flashlight,
- wherein said flash fixation device comprising:
- a flash fixation unit for emitting said flashlight;
- a gas suction unit for sucking vapor gas produced in flash fixation, being disposed at the downstream side toward said medium transportation direction of said flash fixation unit;
- and
- a gas blast mechanism for sucking vapor gas produced in flash fixation, being disposed at the downstream side of said gas suction unit for blasting gas to said medium.
