    • 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.
    • 图像形成装置包括:可旋转带,其具有接缝部分和附接到接缝部分的加强部件; 滚筒用于支撑和喂带; 以及图像形成装置,用于在所述带上或由其承载的记录材料上形成图像,其中,所述加强构件布置在所述带上,使得其穿过与所述带的旋转方向垂直的方向。 缝合部分平行于垂直于带的旋转方向的方向。 加强构件包括相对于与旋转方向垂直的方向的带的两端处的折叠部分,折叠部分通过从带的正面到背面折叠加强构件的端部而形成。 加强构件的端部布置成使得带的正面上的端部和其相反侧上的端部彼此不精确地重叠,但是相对于带的旋转方向不对齐。 该装置还具有用于清洁带的清洁刮板,其中该清洁刮板与带接触的线平行于与带的旋转方向垂直的方向,以及多个图像承载部件,其中 多个颜色的图像从这些图像承载部件传送到由带传送的记录材料。
