ABSTRACT:
A sheet feeding apparatus for an image forming device prevents a sheet jammed in a pickup roller from being damaged when a sheet feeding cassette is separated to remove the jammed sheet. The sheet feeding apparatus for the image forming device includes a sheet feeding cassette being removably installed in the image forming device and having a handle hole for adhesion and removal, a sheet pressure plate hinge-fixed in the sheet feeding cassette, to load and support sheets, an elastic member to elastically support the sheet pressure plate to be upwardly slanted, and a down lever installed at the lower portion of the sheet pressure plate to be moved forward or backward. When the down lever is pulled through the handle hole, the sheet pressure plate is downwardly rotated to compress the elastic member, and when the down lever is pushed, the sheet pressure plate returns to the original position by the elastic member.
