AI Technical Summary
Existing fixing devices in electrophotographic image forming apparatuses face challenges in temperature control performance, leading to temperature drops in the fixing nip, which can cause fixing failures due to inadequate heat supply management.
A heating device with a rotating member, a heater inside its loop, a pressing member, a nip formation member, and two temperature sensors to detect the temperature of the nip formation member and the rotating member, allowing for precise control of the heat transfer and power adjustment to maintain optimal temperature.
This configuration enhances temperature control performance, prevents fixing failures caused by temperature drops, and reduces unnecessary power consumption by optimizing heat transfer efficiency between the nip formation member and the rotating member.
