A feeding device includes a rotation shaft, a feeding roller that includes a through-hole and that is attached to an attachment position of the rotation shaft by moving along the rotation shaft from one end side of the through-hole through the rotation shaft in a case of attachment, and a stop mechanism that stops movement of the feeding roller before the feeding roller moves to the attachment position in a case of being moved along the rotation shaft from the other end side of the through-hole of the feeding roller through the rotation shaft.
