A hinge unit applies resilience differently according to the angle at which the hinge unit is opened, and an image forming apparatus has a cover attached by the hinge unit. The hinge unit includes a lower frame connected to a scan unit of a main body of an apparatus; an upper frame engaged with the lower frame through a hinge shaft and connected to a cover; and first and second resilient members serially arranged within the upper frame. When the cover pivots toward the scan unit at less than a predetermined angle, the hinge unit provides relatively minor resistance, whereas when the cover pivots toward the scan unit at the predetermined angle or greater, the hinge unit provides relatively greater resistance, thereby appropriately coping with the moment by weight of the cover. As a result, the improved hinge unit may enable a user to open and close the cover more comfortably.

A hinge includes a housing. A stopper plugging up one end of the housing defines a through-hole. A sliding cam slideably received in the housing defines concave portions on a top surface thereof and an axial hole. A rotatable cam has a base portion extending downward to form pushing portions disposed in the concave portions. The base portion defines a receiving hole. A top surface of the base portion protrudes upward and defines a stepped portion. A spring is slideably received in the housing. One end of the spring is fixed on the sliding cam and the other end of the spring is fastened around the stopper. A shaft received in the housing runs through the axial hole, the spring and the through-hole. An end of the shaft is fixed with the stopper, and an opposite end of the shaft is received in the receiving hole. A damper has a top wall extending downward to form an enclosure. A top surface of the top wall protrudes upward to form a preventing block. A bottom surface of the top wall extends downward to form mounting portions. The mounting portions are encircled in the enclosure and match with the stepped portion. A cap rotatablely receiving the damper defines an accommodating space. A part of the accommodating space forms a restraining portion.
