おそれがある。This type of transfer device is a roller-shaped transfer roller in which a conductive shaft (conductive substrate) is covered with semiconductive foamed rubber. Although the toner that has adhered is wiped off, the toner that cannot be completely cleaned remains on the foamed rubber on the surface of the transfer roller, causing transfer unevenness and stains on the back of the paper. Further, since the transfer roller is in contact with the photosensitive drum through the paper, various problems due to this,
For example, a problem such as whether or not the paper can reliably pass through the transfer area may occur when the paper passes through the transfer area.

It is a roller-shaped transfer roller with foamed rubber on the surface.To prevent toner stains, the transfer roller is rotated in advance before transfer to deal with the chamfering effect. Although the transfer roller surface is made of foamed rubber, it is difficult to wipe off the toner adhering to the foamed rubber on the surface of the transfer roller due to a jam or the like, though it is effective against dirt. Therefore, there is still a possibility that uneven transfer and backside stain of the paper may occur.
