Abstract
An image forming apparatus includes a recording sheet supplying portion for supplying a recording sheet and an image forming device for forming an image on the recording sheet supplied from the recording sheet supplying portion. A main power source supplies electric power to the image forming device and thermal fixing device. A recording sheet detector detects whether the recording sheet is present on the recording sheet supplying portion and a sub-power source supplies electric power to the recording sheet detector. A main power source switch automatically activates the main power source when the recording sheet detector detects the presence of the recording sheet or an image formation signal is inputted. The image forming apparatus does not include a main power switch to manually control the main power source.
