Abstract
An image forming apparatus includes a photosensitive drum and a fuser. The fuser includes an upper frame. The upper frame includes an upper first rib downstream of a heating rotating member in a sheet conveying direction, an upper second rib adjacent to the upper first rib in a width direction perpendicular to the sheet conveying direction, and first and second conveying rollers. The upper first rib includes a first guide surface, and a separation surface. The upper second rib includes a second guide surface. The second guide surface is located downstream of the first guide surface in the sheet conveying direction. A distance between a nip point between the first and second conveying rollers and the second guide surface in a direction perpendicular to the sheet conveying direction and the width direction is smaller than a distance between the nip point and the separation surface.
