摘要： In a fixing device, a core material of a fixing rotating member has two largest-diameter portions respectively located between a central portion and each end portion of the fixing rotating member, within a region where a recording material of a largest size passes, and the diameter of each core material is gradually reduced from the largest-diameter portion toward the central portion and toward the nearest end portion. The outer shape of the fixing rotating member conforms to the shape of the core material. According to this configuration, it is possible to prevent corrugation and curl of the recording material, and to provide excellent mountability of the recording material.

In order to obtain a stable heating property (fixing property) not depending on the kind of paper of a recording material (a smooth paper, a rough paper), the temperature of the heating member or the heating rotary member is detected, and the current to the heating member is controlled so that the detected temperature becomes a target temperature. In this situation, the supply power amount to the heating member is monitored, and the target temperature is corrected on the basis of the monitor result. Also, when the temperature detected by the temperature detecting device is within a given range, the current to the heating member is controlled so that a given power is supplied to the heating member.
