Abstract

A control method of an image forming apparatus including a fixing device including a fixing rotator includes starting warming up the fixing device; detecting at least one of an electric voltage, an electric current, and an electric power input to the image forming apparatus when the fixing device is warmed up; detecting a temperature of the fixing rotator when the fixing device is warmed up; determining that the image forming apparatus is in a low input state that does not satisfy a predetermined input condition based on the detected one of the electric voltage, the electric current, and the electric power; determining that the fixing rotator is in a low temperature state that does not satisfy a predetermined heating condition based on the detected temperature of the fixing rotator; and issuing a notification that urges a recovery operation of the fixing device.

Description

technical field [0001] The present invention relates to a control method of an image forming apparatus in a copier, a printer, a facsimile, or their multifunction peripherals. Background technique [0002] In the fixing device installed in the image forming apparatus, when the fixing member is heated by the heating source to a required temperature, the temperature of the fixing member may be in a low heating state without sufficient temperature rise due to the heating source. [0003] For such a low heating state, as a control method of a conventional image forming apparatus, for example, during the start operation of the fixing device when the image forming apparatus is started, the temperature of the fixing member is detected, and when the temperature is lower than a specified reference value, the temperature of the fixing member is detected. Low heating state. [0004] Then, when the low heating state is detected, it is judged as an abnormality of the image forming appar...
