摘要： The present invention relates to a benzidine derivative represented by the general formula (3): wherein R 17 to R 24 are as defined in the present specification. The invention also relates to a benzidine derivative represented by the general formulae (3'), (4), (5) and (6), disclosed herein. The benzidine derivatives improve durability and heat resistance of a membrane containing the same while maintaining high hole transferring capability. Therefore, an electrophotosensitive material, which comprises a photosensitive layer containing the benzidine derivative, has high sensitivity and is superior in durability and heat resistance.

摘要： A fixation temperature control device is to be applied to a copying machine or the like. A control section determines a heat roller control temperature (T P-H ) in consideration of a detected press roller temperature (T P2 ). When the heat roller temperature (T P1 ) is lower than a reference temperature (T PTH ), a correction value (E1) is added to a heat roller reference temperature (T HCON ) to set the heat roller control temperature (T P-H ) higher than usual. When a fixing unit (35) is in a stand-by status and the press roller temperature (T P2 ) is in a temperature range between 80°C and 90°C, a heat roller (38) and a press roller (37) are preferably rotated at a speed lower than a usual rotational speed.
