Description
【００４０】
【発明の効果】
以上説明したように、本発明によれば、ベルト搬送装置の張架ロールの両端位置を芯出し位置拘束手段で拘束するようにしたので、ロール保持部材に対して張架ロールを軸方向にがたつくことなく位置拘束し、回転支承することができる。このため、搬送ベルトの蛇行によって張架ロールが軸方向に移動する事態を有効に阻止することが可能になり、その分、張架ロールに掛け渡される搬送ベルトの片寄りや蛇行を効果的に抑制することができ、搬送ベルトを定められた経路上に正確に循環搬送することができる。
特に、搬送ベルト上に直接若しくは記録材を介して複数の色成分画像を重ね転写する画像形成装置にあっては、搬送ベルトの蛇行を効果的に抑制できるため、各色成分画像の相互の位置合せを正確に一致させることが可能になり、色ずれのない高品質のカラー画像を得ることができる。[0040]
【Effect of the invention】
As described above, according to the present invention, since the both end positions of the tension roll belt conveying apparatus so as to restrain in the centering position restraint, rattling the tension roll in the axial direction relative to the roll holder It can be position-restrained and rotatably supported without. For this reason, it is possible to effectively prevent the tension roll from moving in the axial direction by the meandering of the conveyance belt, and the deviation or meandering of the conveyance belt stretched around the tension roll is effectively achieved by that amount. Thus, the conveyor belt can be accurately circulated and conveyed along a predetermined path.
In particular, in an image forming apparatus in which a plurality of color component images are overlapped and transferred directly onto a conveyance belt or via a recording material, the meandering of the conveyance belt can be effectively suppressed, so mutual alignment of each color component image Can be accurately matched, and high-quality color images without color misregistration can be obtained.
