Patent ID: 7054573

Claim:
A heating apparatus having a heating member disposed while being fixedly supported, a moving member sliding relative to said heating member, and a pressure member brought into pressure contact with said heating member with said moving member interposed therebetween to thereby form a nip, wherein a material to be heated is introduced between the moving member and the pressure member in said nip and is nipped and transported therebetween and is heated by heat from the heating member transmitted through the moving member, said heating apparatus comprising: first temperature detecting means disposed in proximity to or in contact with said moving member; second temperature detecting means for detecting a temperature of said heating member or an atmospheric temperature of said apparatus; controlling means for controlling electric power supply to said heating member on the basis of a result of detection by said first temperature detecting means; and judging means for judging on the basis of a result of detection by said second temperature detecting means whether electrical energization of said heating member should be effected before the start of movement driving of said moving member.
