摘要： A printing medium alignment device and an image forming apparatus having the same, the image forming apparatus includes a printing medium supply unit to supply a printing medium, a printing unit to print an image on the printing medium supplied from the printing medium supply unit, and a printing medium alignment device to align the printing medium fed toward the printing unit. The printing medium alignment device includes: a register roller; an idle roller to form a nip with the register roller, to feed the printing medium to the printing unit; a register to move to a first position to block the printing medium from entering the nip, to align the printing medium, and to move to a second position to allow the printing medium to enter the nip; and a shutter roller mounted in the register shutter. When the register shutter is in the second position, the shutter roller rolls while in contact with the printing medium, to decrease a friction between the printing medium and the register shutter.
