Abstract
A fusing apparatus operable at a desired fusing temperature through a run period when toner images on a receiver or copy sheet are fused, using up a required and first amount of heat, and through a standby period when the apparatus is awaiting a run period. The fusing apparatus includes a device for selectively dissipating, during the standby period, a desired and second amount of heat approximating the required and first amount of heat used up during the run period. The heat dissipating device thus prevents 'droop' or a dropping from the desired fusing temperature, by causing heat flow from the apparatus to remain relatively constant during both run and standby periods. Additionally, such dissipation also advantageously cools the apparatus, thereby preventing the occurrence of heat-related fusing defects such as copy curling, blistering, and image offset.
