An image forming apparatus having a timer function includes a main switch for manually switching between supply and interruption of electric power to the apparatus, a detector for detecting whether the main switch is in a power-interruption state or in a power-supply state, a memory for storing a state indicating that the main switch is in a power-interruption state when it has been detected that the main switch is in a power-interruption state, a controller for placing the apparatus in a standby state in which an image can be formed or in a shutdown state in which an image cannot be formed during a preset time period, and a power supply for supplying power to the controller, wherein the apparatus is placed in a standby state even by a set shutdown time period in the case a power-interruption state is stored and wherein the apparatus is placed in a shutdown state during the set shutdown time period in the case the power-interruption state is not stored.
An image forming apparatus comprising:
An image forming apparatus comprising:
A start control method in an image forming apparatus comprising a main switch for manually switching between supply and interruption of electric power to the apparatus, detection means for detecting whether the main switch is in a power-interruption state or in a power-supply state, non-volatile storage means for storing that the main switch is in a power-interruption state when the detection means has detected that the main switch is in the power-interruption state, control means for placing the apparatus in a standby state in which an image can be formed or in a shutdown state in which an image cannot be formed, during a preset time period, and supply means for supplying the control means with electric power, said method comprising the steps of:
A starting control method in an image forming apparatus comprising a plug for inputting electric power to said apparatus from a source external to said apparatus, a manually operated main switch for switching on or off the electric power input by said plug to said apparatus, and control means for placing said apparatus in a standby state in which an image can be formed or in a shutdown state in which an image cannot be formed, during a preset time zone, said method comprising steps of:
