Claims (1)
検出する温度センサーと、感光体の回転状態の有
無を検出する回転検知センサーと、これら２つの
センサーからの出力信号に応じて加熱手段の通電
量を制御する通電制御回路とを感光体内に設け、
前記回転検知センサーに対向して被検出部を感光
体外に設けたことを特徴とする感光体の温度制御
装置。 A heating means that heats the photoreceptor, a temperature sensor that detects the temperature of the photoreceptor, a rotation detection sensor that detects whether or not the photoreceptor is rotating, and energization of the heating means in accordance with output signals from these two sensors. A energization control circuit for controlling the amount is provided inside the photoreceptor,
A temperature control device for a photoreceptor, characterized in that a detected portion is provided outside the photoreceptor so as to face the rotation detection sensor.
