Benefits of technology

[0009]Accordingly, the present general inventive concept provides an image forming apparatus which power consumption in a standby mode can be minimized and simultaneously a power mode conversion event can be properly considered, in controlling the power mode conversion control.

Problems solved by technology

In conventional image forming apparatuses including a printer, a multi-function device, such a configuration to perform an image forming operation consumes a large amount of power.
However, power consumption even to operate the standby mode control means is unavoidable.
