ABSTRACT:
In a thermal printing device for an image forming apparatus, a heat generating member is implemented as a hollow heat roller having a heating layer thereon. A first member is disposed in the hollow heat roller while. A press roller or second pressing member is located outside of the heat roller while at least partly corresponding to the heat roller. A biasing mechanism biases at least one of the pressing member and press roller toward the other, so that the heat roller is pressed against the pressing member o r the press roller. The device reduces a warm-up time and generates a desired amount of heat with a minimum of power.
