ABSTRACT:
An end fence for use in a sheet feeding cassette includes an end fence main body attached to the sheet feeding cassette and movable along a sheet feeding direction, a device that fixes the end fence main body at any desired position in the sheet feeding cassette, and a sheet pressing element that presses against trailing edges of the sheets loaded on a bottom plate of the sheet feeding cassette. The sheet pressing element is provided to the end fence main body and movable in the sheet feeding direction and protrudes from the end fence main body forward in the sheet feeding direction when the sheet pressing element moves in the sheet feeding direction. The end fence further includes a biasing device that biases the sheet pressing element forward in the sheet feeding direction, and a bias force switching device that switches between a biasing condition and a non-biasing condition.
