摘要： The image forming apparatus is capable of preventing contamination of the rear surface of paper while minimizing the deterioration of the surface of the transfer roll. The image forming apparatus has an intermediate transfer belt for carrying a toner image visualized by a toner, a transfer roll pressed against the intermediate transfer belt, and a cleaning brush that is rotatable in contact with the transfer roll. This transfer roll acts to transfer the toner image carried on the belt to paper. The cleaning brush makes contact with the transfer roll to stir the toner adhering to the transfer roll.

摘要： In an image forming apparatus adapted to transfer a toner image formed on a photosensitive drum to an intermediate transfer belt, and thereafter to a sheet, the position of one end portion of a backup roll around which the intermediate transfer belt is passed is set regulatable, this end portion being fixed after the position thereof has been regulated. The position of one end portion of a driving roll, cleaning blades or photosensitive drum may be set regulatable. This arrangement enables the skew of an image formed on a sheet to be reduced.

摘要： A transfer device includes a photosensitive drum on the outer surface of which an image to be transferred is formed; a transfer drum arranged in parallel to the photosensitive drum and substantially in contact with the outer surface of the photosensitive drum, the transfer drum capable of adsorbing a sheet on its outer surface; and a sheet guide for guiding the sheet supplied toward the transfer drum to a transfer position between the photosensitive drum and the transfer drum. At an end of the sheet guide on the side of the transfer position, a hill-shaped guide is provided which flexes at a flexing point in a plane orthogonal to the rotary axis of each of both drums so as to be convex toward the photosensitive drum. The side of the hill-shaped guide from the flexing point toward, and closest to, the transfer position is inclined toward the photosensitive drum with respect to a tangent of the photosensitive drum passing the transfer position.
