Abstract
A heating and fixing device for toner particles is provided, which includes a pressing element, at least one elastic element, a tube-shaped film, and a pressing roller. The elastic element is provided for generating force to press the pressing element constantly. The heating element is provided for heating the pressing element through the heated side. The film is disposed around the pressing element and the heating element, wherein the film slides relative to the pressing element, and the pressing element presses against the film from the inner side of the film and transfers heat to the film by heat conduction. The pressing element presses the film to contact the pressing roller, so that the recording medium is pressed and heated when traveled between the pressing roller and the film.
Claims12
A heating and fixing device for toner particles, comprising:
- a blade disposed along a longitudinal axis of a tube-shaped film, the blade having a heated side, a contact side and two supporting ribs formed on the heated side of the blade along the longitudinal axis;
- at least one elastic element, for pressing against upper edges of the two supporting ribs;
- a heating element located between the two supporting ribs, for heating the blade through the heated side;
- a tube-shaped film, disposed around the blade and the heating element, sliding relative to the blade, wherein the contact side presses against the inner side of the film constantly and transfers heat to the film by heat conduction;
- and
- a pressing roller, provided corresponding to the contact side, wherein the contact side of the blade presses the film to press against the pressing roller, such that the film presses and heats a recording medium with toner particles passing between the pressing roller and the tube-shaped film, and the pressing roller rotates to drive the tube-shaped film to move together with the recording medium.
