摘要： The present invention is aimed at providing a control system for a thermal fixing apparatus having an excellent fixing ability even at an initial stage of a copying process when applied to a high speed copying machine and ensuring a longer life of a surface layer member of the roller, while maintaining the economical benefit derived from the provision of a heater only in a heat roller. The fixing apparatus includes a heater roller 101 and a press roller 102. At least one of the rollers is driven by a motor 103 while in contact with the other so that both rollers are rotated together. A surface temperature of the heater roller 101 is detected by a thermometer 104 and is used for controlling a heating level of a heater 106 by a controller 105. A standby stage controller 110 stops the rotation of the motor 103 if it is determined that the surface temperature of the press roller detected by a thermometer 107 is higher than the upper limit temperature, and outputs a command for rotating the motor 103 if it is determined that the surface temperature of the press roller is lower than the lower limit temperature.

摘要： In electrophotographic apparatus of the type wherein a light image is projected upon a sensitized photosensitive sheet carried by a rotary drum to form an electrostatic latent image, the latent image is developed into a visible toner image and the toner image is transfer printed onto a recording paper, means is provided for permitting projection of the light image only when other devices of the apparatus tending to produce shock or vibration are not operated and for feeding the recording paper in exact synchronism with the rotation of the drum.
