Abstract
A printing medium supply device and an image forming apparatus having the same are provided. The printing medium supply device may include a pickup unit and an adjustment unit. The pickup unit may include a shaft, a pickup roller spaced apart from the shaft to come into contact with printing media, a pickup holder to support the pickup roller, the pickup holder being rotated about the shaft to lift or lower the pickup roller, and a link member connected to the pickup holder so as to be rotated about the shaft. The adjustment unit may include a pressure member coming into contact with a pressure applied portion of the link member to rotate the link member by applying pressure thereto, and an elastic member elastically supported by the pressure member to transmit elastic force to the link member. This configuration ensures constant pickup pressure despite variation in the quantity of printing media.
