Image Forming Apparatus and Power Control Method Thereof

摘要

An image forming apparatus including: a body; an electronic unit (242/244/246); a replaceable unit (160) that is detachably installed within the body; a power supply (220) that generates and outputs a predetermined operation voltage; a high voltage generating part (232) that receives the operation voltage and generates and outputs a high voltage; an electronic unit driving part (240) that receives the operation voltage and regulates a driving voltage supplied to the electronic unit (242/244/246); and a controller (280) that controls the power supply (220) to cut off the operation voltage if the replaceable unit (160) is not installed within the body. Also taught is a method of operating the image forming apparatus.
