の直後にある、互いに圧接して回転する熱ロール、押付
ロール間を通して定着する電子写真装置において、用紙
を予熱する予熱板に、予熱板の温度を制御する温度セン
サと、用紙の温度を検出する温度センサを設けたことを
特徴とする定着装置。In order to fix the toner image on the paper, the paper is preheated, and in an electrophotographic device, the toner image is fixed by passing it between a heating roll that rotates in pressure contact with each other and a pressing roll immediately after the paper, and a preheating plate that preheats the paper. A fixing device comprising: a temperature sensor for controlling the temperature of the paper; and a temperature sensor for detecting the temperature of the paper.
