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.

The present invention provides a carbon heating element having an arbitrary specific resistance and an arbitrary shape which are arbitrary necessary as a heating element, and a method of producing the same. The carbon heating element is obtained by uniformly dispersing one or at least two metal or metalloid compounds into a composition having shapability and showing a high yield of a carbon residue after firing, shaping the dispersed material-containing mixture thus obtained, and firing the shaped material under a nonoxidizing atmosphere.

Carbonization is achieved and impurity elements are removed by combination of a metal or metalloid compound with a composition exhibiting a carbon residual yield that is substantially not zero after firing, followed by firing at a pressure of no higher than 1×10−2 Pa and a temperature of from 1500° C. to 2200° C.

A thermal printer free of the unevenness of an image is devised so that dust is prevented from adhering to an ink ribbon. In the thermal printer for generating a color image on a recording material by a thermal head and others using an ink ribbon, the ink ribbon is automatically rewound by a length within one image plane and kept on standby after printing is finished and at the time of next printing, the ink ribbon is automatically let out by the length formerly rewound and gets ready for printing.

A thin-film thermal head incorporating a resistance heating layer; and a conductor layer, wherein the main component of the conductor layer is a Cu—Ag alloy. More particularly, the conductor layer contains Cu by 50 atom % or higher, Ag by 0.5 atom % or higher and 50 atom % or lower and other elements by 2 atom % or lower.
