A paper feed apparatus includes a paper feeding portion that sends-out a paper placed in a paper placing tray, and is used in an image forming apparatus such as a multifunction machine. The paper feed apparatus comprises a first regulating portion and a second regulating portion that are arranged in the vicinity of a downstream side of a paper feeding position by the paper feeding portion. The first regulating portion is arranged outside a second width paper passage area to regulate a movement of a first width paper such as A4 paper placed in the paper placing tray toward a feeding direction. On the other hand, the second regulating portion is arranged inside the second width paper passage area to regulate a movement of a second width paper such as a name card placed in the paper placing tray toward a feeding direction. Since there are provided with the first regulating portion and the second regulating portion that are arranged outside and inside the second width paper passage area, the second width paper such as a name card can be adequately fed in addition to the first width paper such as A4 paper.
