Abstract
Disclosed is a fixing device using fuzzy inference, which is used for copying machine, optical printer, or the like. The fixing device is provided with a fixing heater drive circuit 13 for controlling a heater 8 arranged in a fixing roller 9 on the basis of signals from CPU 1. The CPU 1 executes fuzzy inference so as to maintain the heat amount within predetermined value.
Claims9
A fixing device comprising:
- a heating member for thermally fixing an image on a recording medium;
- condition variable detection means for detecting a condition variable, wherein said condition variable is a power source voltage value;
- inference means for fuzzy-inferring a control variable associated with energization to said heating member from the condition variable detected by said condition variable detection means;
- and
- control means for executing control associated with energization to said heating member using the control variable inferred by said inference means.
