  • Publication number: 20150266682
    Abstract: An image forming apparatus includes a printer, a lower feeding roller that feeds a sheet, a bearing that rotatably supports the lower feeding roller with respect to a housing, a belt rotating mechanism including a belt disposed over the lower feeding roller and driving the lower feeding roller, and a leaf spring that biases the lower feeding roller in a direction opposite to the direction of deformation of the feeding roller caused by the tension of the belt. The belt is arranged on the outer side in the axial direction of the lower feeding roller with respect to the bearing. The leaf spring is arranged on the outer side in the axial direction of the lower feeding roller with respect to the belt, so that the leaf spring biases the lower feeding roller.
