Claim:
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.
