Image forming apparatus |
摘要 |
An image forming apparatus aims at eliminating a possibility of causing deterioration in conveying and scratching off toners on a recording medium by smoothly rotating a driven roller corresponding to rotations of a driving roller. Rubber rings spaced away in an axial direction from the driving roller are fitted to a shaft of a driven roller brought into contact with the driving roller. A record sheet conveyed with rotations of the driving roller rotates the rubber rings, whereby the driven roller can be surely rotated.
