The present invention relates to an apparatus for elevating a paper feeding/ejecting roller of an image forming apparatus, including: pressing bumps which are prepared on the side of a cassette tray; a bundle of rollers which is installed on a cassette tray insertion frame where the cassette tray is inserted, for feeding and ejecting paper loaded on the cassette tray; and a roller bundle elevation device which descends the bundled rollers when the cassette tray is inserted, by being pressed of the pressing bumps, and which elevates the bundled rollers when the cassette tray is ejected. When opening and closing the cassette tray, the roller bundle elevation can be either moved up or down, so as to avoid the intervention between the roller bundle and paper, and set the roller bundle to a normal position, wherein the feeding and ejecting of paper is capable. |
