Description

  The present invention relates to an image forming apparatus such as a multi-function digital multi-function peripheral employing an electrophotographic process, a mode transition control method and a mode transition control program in the apparatus.

  An image forming apparatus employing an electrophotographic process generally tends to consume a relatively large amount of power for heating the fixing roller even in a standby state. For this reason, when not used, power consumption can be effectively suppressed by turning off the power supply so as not to energize the fixing roller.

  Conventionally, when an image forming apparatus is not operated for a certain period of time, a function that automatically turns off the power (sleep timer) and a function that enters a standby mode such as turning off the power by a user operation has been widely used. ing.

  However, in order to use the image forming apparatus again after it is turned off, when the user turns on the power, it takes a considerable time to reach the normal mode in which the image forming apparatus can be used, which is inconvenient.

  In order to avoid the inconvenience that it takes time to reach the normal mode in this way, the power is automatically turned off by the weekly timer function (for example, the function that can automatically turn the power on / off every day / day of the week). A device in which the / ON timing is set in advance has been put into practical use. If this function is used, the power OFF / ON of the image forming apparatus can be automatically controlled according to the set timing.

  In addition, when the number of times the power is turned ON / OFF becomes a predetermined number before the time set by the weekly timer, a technique for prompting a change of the set time by a notification operation means such as a display screen Is disclosed (for example, see Patent Document 1).
