An image forming apparatus includes a belt, an image forming unit, first roller and second rollers, a feeding portion, a stretching roller and an urging member. A contact point between an outer common tangential line between the stretching roller and the first transfer roller and the first transfer roller and an intersection point between the outer common tangential line and a rectilinear line perpendicular to the outer common tangential line and passing through a rotation center of the second transfer roller satisfy that the contact point is closer to the stretching roller than the intersection point is and that a distance between the contact point and the intersection point is 5 % or more of a diameter of the first transfer roller. The urging member urges the belt from an inner peripheral belt surface at a position, close to a transfer portion, between the first roller and the belt. |
