A registration device usable with an image forming apparatus includes a registration roller, a registration lever to rotate between an alignment position to block and align a leading edge of a paper sheet supplied to the registration roller and an opening position to allow the paper sheet to be fed beyond the registration lever, and a resilient member to resiliently urge the registration lever to rotate into the alignment position. The resilient member has a center portion and first and second arms extending from the center portion. An end of the first arm is coupled to the registration lever and the resilient member is pivotable about an end of the second arm.
