PURPOSE:To reduce a curling amount regardless of the direction of the curling of a paper by providing a roller train consisting of five or more rollers in a both-side paper carrying path. CONSTITUTION:The roller train 30 consisting of five or more rollers is provided in the both-side paper carrying guide 23, and the curling of the paper is corrected by allowing the paper to pass through the roller train 30. Intermediate rollers 32-35 are rubber rollers consisting of the identical material and having the equal diameter, the equal hardness of rubber and the same arrangement of the rubber in an axial direction. As to rollers 31 and 36 at both ends, the material and the diameter thereof are not always equal to those of the intermedi ate roller. The rollers 32-35 are respectively and independently pressurized by uniform pressure leaf springs 38-41. Then, carrying performance for a transfer paper n the roller train 30 is improved owing to paper guides 42-45. |
