    • A fixing device includes a fixing member that fixes a toner image on a recording material, a pressure applying member that is pressed against an outer peripheral surface of the fixing member and forms a press-fixing part therebetween through which the recording material having an unfixed toner image is transported, a heating unit that heats the fixing member, and a pressure-applying-member-moving unit that moves the pressure applying member and changes the pressure applying member between being pressed against the outer peripheral surface of the fixing member and being spaced apart from the outer peripheral surface of the fixing member. The heating unit heats the fixing member at the start of a fixing operation under heating conditions corresponding to a change in the state of the fixing member occurring when the pressure applying member is pressed against the outer peripheral surface of the fixing member by the pressure-applying-member-moving unit.
    • 定影装置包括将调色剂图像固定在记录材料上的固定构件,压力施加构件,其被压靠在固定构件的外周表面上并在其间形成压力固定部分,通过该压力固定部件具有未定影调色剂的记录材料 图像传送,加热固定构件的加热单元和压力施加构件移动单元,该压力施加构件移动单元使压力施加构件移动,并且在压紧施加构件被压靠在固定构件的外周表面之间并且间隔开 除了固定构件的外周表面之外。 加热单元在与加压条件相对应的加热条件下加热固定部件,所述加热条件与通过施加压力而将压力施加部件压靠在固定部件的外周面上时发生的固定部件的状态的变化相对应 成员移动单位。
