Description
本発明は、画像形成装置に関する。 The present invention relates to an image forming apparatus .
本発明は、転写媒体が転写部を通過するときの前記転写媒体の転写ローラへの巻き付き量の違いを抑制することが可能な画像形成装置を提供することを目的とする。 An object of the present invention is to provide an image forming apparatus capable of suppressing a difference in the amount of winding of the transfer medium around a transfer roller when the transfer medium passes through a transfer portion .
上記課題を解決するために、本発明に係る画像形成装置は、第１の支持ローラの配置方向から前記第１の支持ローラに隣接して配置された第２の支持ローラの配置方向に向かって回転するように、複数の支持ローラに掛け渡された中間転写ベルトと、前記中間転写ベルトを介して前記第２の支持ローラを押圧するように配置され前記中間転写ベルトとにより転写部を形成するための転写ローラと、前記中間転写ベルトにおける前記第１の支持ローラによって支持される位置から前記転写部までの走行軌跡と前記転写部に搬送されてくる転写媒体の搬送経路との成す角が前記転写媒体の性状に応じて変化するように、前記第１の支持ローラを移動させる支持ローラ移動手段と、を備え、前記転写ローラは、前記支持ローラ移動手段により前記第１の支持ローラが移動されるのに伴って配置位置が所定の方向に移動するように構成されていることを特徴とする。 In order to solve the above-described problem, an image forming apparatus according to the present invention is directed from an arrangement direction of a first support roller toward an arrangement direction of a second support roller arranged adjacent to the first support roller. A transfer portion is formed by the intermediate transfer belt that is stretched over a plurality of support rollers so as to rotate, and the intermediate transfer belt that is arranged to press the second support roller via the intermediate transfer belt. And an angle formed by a travel locus from a position supported by the first support roller on the intermediate transfer belt to the transfer unit and a transfer path of the transfer medium conveyed to the transfer unit. Support roller moving means for moving the first support roller so as to change according to the properties of the transfer medium, and the transfer roller is moved by the support roller moving means. Positions with for support rollers are moved, characterized in that it is configured to move in a predetermined direction.
