Patent ID: 7389433

Claim:
An image forming system, comprising: an image forming portion which carries out image formation processing where an image is formed on a recording medium on the basis of image information and is provided with a drive motor portion for driving predetermined mechanisms employed in the image formation processing and a control sensor portion for controlling the predetermined mechanisms, and a power source portion for supplying electric power to the image forming portion, wherein the improvement comprises: a start instruction detecting portion which detects a start instruction to start the image formation processing; a power source control portion which inhibits the power source portion from supplying the electric power to the drive motor portion and/or the control sensor portion before the start instruction detecting portion detects the start instruction when the image formation processing is not being performed; an operation detecting portion which detects a predetermined operation by an operator before the start instruction detecting portion detects the start instruction when the image formation processing is not being performed; and wherein the power source control portion continues to inhibit the power source portion from supplying the electric power to the drive motor portion and/or the control sensor portion while the image forming system is in a waiting state from the time when the operation detecting portion detects a predetermined operation to the time when the start instruction detecting portion first detects the start instruction after detection of the predetermined operation.
