Abstract
PURPOSE: To make feed electric power even and prevent the occurrence of the yellowing and scorching of paper on a fixing plate by making the set temperature on the inlet side of the heat fixing plate lower than that on the outlet side.
CONSTITUTION: It is assumed that unifixed paper is conveyed to the heat-fixing plate 1 consisting of discrete heater blocks from the arrow 4 direction. Heating heaters 2 and back surface temperature controlling thermistors 3 are buried separately in the fixing plate. With the suitable resistance values of the thermistors 3 as boundaries, the supply of electric power to the heaters and its stoppage are done. The set temperatures from the inlet side to outlet side are assumed to be, for example, 3 steps, and the set temperature on the inlet side is made lower than that of the outlet side. As a result of this, the required electric power of the inlet side fixing heating plates becomes lower and the entire required electric power is supplied evenly over the entire part of the heating plates, thus the occurrence of yellowing and scorching of the paper on the inlet side fixing plate may be prevented.
