  • Fixing For Electrophotography (AREA)

Abstract

PURPOSE: To enable the obtaining of fixing of high quality over the entire surface of copying paper by holding a fixing roller static until the toners soften at least.
CONSTITUTION: When the electric power source of the copying machine is turned on, a heater 5 is warmed up by a temperature control circuit 43. At 100°C or less of the surface temperature of a fixing roller 3, the output line l1 is low level and the output of an AND gate 45 is low level as well, at which an electromagnetic clutch 38 is held de-energized and shut off. Similarly, the output line l2 is low level as well and a main driving means 25 is held disabled. When the surface temperature of the fixing roller 3 becomes 100°C or more, the line l1 becomes high level and the line l2 is held at low level and therefore the driving circuit is abled to put the electromagnetic clutch 38 in connected state. Further, the roller temperature rises and when it becomes e.g. 180°C, the temperature control circuit 43 maintains that temperature at all times and the copying operation becomes possible by the operation of a print button 53.
