An image forming apparatus includes: a rotatable belt having a seamed portion and a reinforcing member attached to the seamed portion; rollers for supporting and feeding the belt; and an image forming device for forming an image on the belt or on a recording material carried thereby, wherein the reinforcing member is arranged on the belt such that it crosses a direction perpendicular to the direction of rotation of the belt. The seamed portion is parallel to the direction perpendicular to the direction of rotation of the belt. The reinforcing member includes folded portions at both ends of the belt with respect to the direction perpendicular to the direction of rotation, the folded portions being formed by folding over the end portions of the reinforcing member from the obverse to the reverse side of the belt. The end portions of the reinforcing member are arranged such that the end portion on the obverse side of the belt and that on the reverse side thereof are not exactly superimposed one upon the other but out of alignment with respect the direction of rotation of the belt. The apparatus further has a cleaning blade for cleaning the belt, wherein the line in which this cleaning blade is in contact with the belt is parallel to the direction perpendicular to the direction of rotation of the belt, and a plurality of image bearing members, wherein images of plurality of colors are transferred from these image bearing members to the recording material carried by the belt.
