A waste toner transporting apparatus which transfers waste toner removed from a photosensitive drum to a waste toner housing is provided. The waste toner transporting apparatus includes a toner transporting plate arranged substantially above a cleaning blade. A transporting member is installed at one end of the toner transporting plate and has a cam follower arranged on an opposite side of the toner transporting plate. A driving cam contacts the cam follower and converts rotational motion into linear reciprocating motion to enable the toner transporting plate to reciprocate on the cleaning blade.
