Abstract
An image forming apparatus having: an endless fixing belt; a heating member heating the fixing belt; a support member maintaining the fixing belt substantially circular; a pressing member in contact with the fixing belt to form a fixing nip portion; a temperature sensor; a position detector; a storage storing temperatures and positions of the fixing belt detected by the temperature sensor and the position detector; and a control unit. The control unit is operable in a characteristic storing mode and in a fixing mode. In the characteristic storing mode, temperatures of the fixing belt associated with positions are detected, and the detected temperatures and positions are stored in the storage. In the fixing mode, temperatures of the fixing nip portion are predicted with reference to the temperatures and positions stored in the storage, and the heating member is controlled such that the predicted temperatures become a target temperature.
