れていることを特徴．とする定着装置。In a fixing device that fixes a toner image on a paper by supporting and conveying the paper on which the toner image has been transferred by a pair of fixing and pressure opening rollers that are in pressure contact with each other, as a pressure member that brings the two rollers into pressure contact with each other. It has a spring made of a shape memory alloy, and the shape memory alloy forming the spring has a transformation temperature that is approximately the temperature of the spring when the temperature of the fixing roller reaches the fixing temperature, and the temperature of the spring is higher than the above transformation temperature. The natural length at temperatures higher than and lower than the transformation temperature is such that the pressing force between the two rollers at a temperature higher than the transformation temperature is lower than the pressing force between the two rollers at a temperature lower than the transformation temperature. The feature is that it is preset. Fixing device.
