Abstract

In the present invention, for the low heating state of the fixing member in the image forming apparatus in the standby state, there is a requirement to provide a control method of the image forming apparatus that can appropriately respond to each cause. In addition to detecting the voltage input to the image forming apparatus (1) in the standby state, the temperature (T) of the fixing roller (18) in the standby state is also detected, and the value obtained from the detected voltage (V) is When the voltage state is a low voltage state that does not satisfy the prescribed voltage conditions, and when the heating state obtained from the detected temperature (T) of the fixing roller (18) is a low heating state that does not satisfy the prescribed heating conditions, the liquid crystal panel A display prompting the recovery operation of the image forming apparatus (1) is executed in (41).

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 some image forming apparatuses related to copiers, printers, facsimiles, or their multifunctional peripherals, if they are not operated for a certain period of time after the image forming operation, a part of the power supply is stopped, and the system moves to the standby mode. Transition to the standby state of one image forming operation. In this standby state, the fixing member is heated by the heating source, and a state in which the temperature of the fixing member is kept at a certain level or higher is maintained. [0003] However, in an image forming apparatus that functions in such a standby state, the temperature of the fixing member may be in a low heating state where the temperature does not rise sufficiently due to a heating source for heating the fixing...
