A recording paper length sensing apparatus for sensing a length of recording paper being fed in a paper feeding direction to an image forming apparatus. The recording paper length sensing apparatus comprises a table part on which the recording paper is loaded, the table part having a movable member and a fixed member and being mounted to a portion of the image forming apparatus to feed the recording paper to the image forming apparatus, a position of the movable member relative to the fixed member being adjustable to make an end portion of the movable member accord with a recording paper edge, a switching part for detecting a predetermined position of the movable member, the switching part being turned ON to generate a signal indicative of the recording paper length when the predetermined position of the movable member is detected, and a control part responsive to the signal from the switching part for recognition of the recording paper length. According to the present invention, it is possible to detect the length of recording paper having several different sizes by a single paper table unit, without using several paper cassettes for several different paper sizes.
