Abstract
The present invention provides an external heating member abutment controller which can instantaneously adjust the quantity of heat provided by external heating members to the surface of a fixing member, to provide a fixing apparatus which can drastically increase productivity for cardboards and which can provide high-quality color images free from variations in gloss (gloss nonuniformity). Thus, a fixing apparatus according to the present invention comprises a first and second fixing rotating members that use nip portions to thermally fix a toner image on a recording material and a first and second heating members that abut against the first fixing rotating member to heat an outer surface of the first fixing rotating member. The fixing apparatus is characterized in that when a fixing operation is started, the first heating member and the second heating member are sequentially abutted against the first fixing rotating member.
