具有邻近容易变形的位置的温度检测器的定影装置和包括其的成像装置

Fixing device with a temperature detector adjacent an easily deformable location and image forming apparatus including same
Abstract:
A fixing device for fixing an unfixed image onto a recording medium includes a fixing belt, a nip forming member, an opposing rotary member, a heater, and a temperature detector. The fixing belt is formed into a loop to move endlessly and fix the unfixed image on the recording medium. The nip forming member is disposed inside the loop formed by the fixing belt. The opposing rotary member contacts the nip forming member via the fixing belt to form a nip portion therebetween while rotating. The heater heats the fixing belt at a place other than the nip portion. The temperature detector detects a temperature of the surface of the fixing belt. The temperature detector detects the temperature near a place of the fixing belt that easily deforms as the fixing belt is heated by the heater.
Abstract(Chinese):

用于将未定影图像固定到记录介质上的定影装置包括定影带，辊隙形成构件，相对旋转构件，加热器和温度检测器。 将定影带形成为环状以循环移动并将未定影图像固定在记录介质上。 辊隙形成构件设置在由定影带形成的环内。 相对的旋转构件经由定影带与辊隙形成构件接触，在旋转的同时在其间形成夹持部。 加热器将定影带加热到夹持部以外的位置。 温度检测器检测定影带的表面的温度。 温度检测器检测定影带靠近加热器加热定影带时容易变形的位置附近的温度。
