Zusammenfassung:To prevent image deviation with a simple configuration without performing complex control.SOLUTION: A K single-color image forming apparatus is formed by using a frame body common to a model of a Y, M, C, K tandem-color image forming apparatus, and comprises: a K image forming unit 10; secondary transfer means 8 that secondarily transfers a toner image transferred onto an intermediate transfer body 7 to a transfer target member; cleaning means 9 that removes transfer residual toner on the intermediate transfer body 7; a fuser 12 that fixes the toner on the transfer target member to the transfer target member; and a roller 11 that is attached, on the intermediate transfer body 7, to the position of any one of Y, M, C in the model of the color image forming apparatus and brought into pressure contact with the intermediate transfer body.SELECTED DRAWING: Figure 1 【課題】複雑な制御を行うことなく、簡易な構成で、画像ずれを防止すること。【解決手段】Y、M、C、Kのタンデムカラー画像形成装置のモデルと共通の枠体を用いて形成される、K単色の画像形成装置において、K画像形成ユニット10と、前記中間転写体7上に転写されたトナー像を被転写部材に2次転写させる2次転写手段8と、前記中間転写体7上の転写残トナーを清掃する清掃手段9と、前記被転写部材上のトナーを被転写部材に定着させる定着器12と、前記中間転写体7上において、前記カラー画像形成装置のモデルにおけるY、M、Cいづれかの位置に取り付けられ、圧接されるローラー11を持つことを特徴とする。【選択図】図1
