Abstract

The invention provides a photographic fixing device which includes a heating element and a roller, the heating element is arranged for emitting heat energy, and the roller comprises a hollow tube body and an air turbulence structure. The hollow tube body is annularly arranged on the outer side of the heating element, and at least partially coats the heating element, an annular region is defined between the hollow tube body and the heating element, and the air turbulence structure is formed on the inner wall of the hollow tube body, and is arranged for disturbing air to convect in the annular region during rotation of the hollow tube body to promote heat transfer efficiency of heat transfer to the hollow tube body, so that the effects of improvement of the heat transfer efficiency and homogeneous temperature distribution of the roller surface can be achieved so as to effectively reduce the power wattage and energy consumption of the heating element.

Description

technical field [0001] The invention relates to a fixing device, in particular to a fixing device and rollers thereof. Background technique [0002] Laser printers are currently the most widely used printing equipment in enterprises and schools. The imaging generation principle is that after the paper is introduced, the laser diode unit will project the laser light containing the image data onto the photosensitive roller, and at the same time, the toner cartridge will be transferred to the photosensitive roller by the roller. The toner is attached to the imaging area of ​​the photosensitive roller, and the toner on the imaging area can be attached to the paper by rotating the photosensitive roller. Finally, the toner is fixed on the paper through the heating and pressure of the fixing device. [0003] In other words, the main imaging method of a laser printer is to use a fixing device to fix toner by means of heating and pressure. Among them, the heating method mostly uses...
