Zusammenfassung:PROBLEM TO BE SOLVED: To provide an image forming apparatus configured to prevent a recording material passing through a transfer nip from being wrinkled.SOLUTION: An image forming apparatus 100 includes: toner-image forming means 7 which forms a toner image; an image carrier 10 for carrying the toner image formed by the toner-image forming means, on a surface; a transfer member 21 which is rotatably arranged around a rotation shaft 21a, and comes into direct or indirect contact with the surface of the image carrier, to form a transfer nip for transferring the toner image to a recording material; and a guide member 43 which guides the recording material in order to convey the recording material toward the transfer nip. The guide member includes a first positioning section 43A which comes into contact with the image carrier or a structure 45 holding the image carrer to position the guide member with respect to the image carrier, and a second positioning section which is held by the rotation shaft to position the guide member with respect to the transfer member. 【課題】転写ニップを通過した記録体に皺が発生するのを抑制できる画像形成装置を提供する。【解決手段】トナー像を形成するトナー像形成手段7と、トナー像形成手段が形成したトナー像を表面に担持する像担持体10と、回転軸21aを中心に回転可能に設けられ像担持体の表面と直接または間接的に接触し記録体上にトナー像を転写する転写ニップを形成する転写部材21と、記録体を転写ニップに向けて搬送するために記録体をガイドするガイド部材43とを備えた画像形成装置100において、像担持体または像担持体を保持する構造体45と接触し像担持体に対するガイド部材の位置決めを行う第一位置決め部43Aと、前記回転軸に保持され転写部材に対するガイド部材の位置決めを行う第二位置決め部とを、ガイド部材に設けた。【選択図】図1
