The motor driver control circuit includes a first H-bridge and a second H-bridge. The first connector is a connector to which an output from the first H-bridge and an output from the second H-bridge are input. The first wire and the second wire input the output from the first H-bridge to the first connector. The third wire and the fourth wire input the output from the second H-bridge to the first connector. The fifth wire is connected to the first wire and outputs the first H-bridge output to another connector. The sixth wire is connected to the second wire and outputs the first H-bridge output to the other connector.

摘要： An image forming apparatus comprises a fixing device comprising a heater for heating a sheet on which an image is formed and a non-volatile memory in which characteristic information of the heater is stored. The fixing device is replaceable. In a case where the fixing device is replaced, the image forming apparatus starts to supply power to the heater before completing to read the characteristic information from the fixing device replaced. Due to this, the image forming apparatus can promptly heat the heater of the fixing device than before.
