摘要
A control portion determines whether a malfunction occurs or not in a roller temperature sensor and an ambient temperature sensor by comparing a trajectory (temporal behavior) actually created by two-dimensional data on a temperature table with a target trajectory. In other words, the control portion successively integrates a prescribed weight for each transition from one element to the adjacent element corresponding to a trajectory of two-dimensional data on the temperature table, and determines whether or not a malfunction occurs in the roller temperature sensor and the ambient temperature sensor, based on the integrated weight.
