PROBLEM TO BE SOLVED: To provide a heating device which employs a simple structure to simultaneously achieve superior fixation performance and power saving because of increased fixation efficiency, device safety assured by damage prevention of a heating element at the time of faulty heating of the heating element and improved reliability, and to provide an image forming device equipped with the heating device. SOLUTION: In a film-heating type heating device and an image forming device equipped with such a heating device, many resistive heating elements whose volume resistances are all identical or close values are arranged symmetrically relative to upstream and downstream in the width direction of the heating elements. The heating device has a means for performing current carry control on many resistive heating elements independently. During operation of the heating device, current carry control is carried out such that the heating values of the upstream resistive heating elements are greater than those of the downstream resistive heating elements.
