摘要： An image forming apparatus for recording on two sides in a single pass, with which the transfer of a toner image onto one side of a recording medium and the transfer of a toner image onto the other side can both be performed under optimal conditions, which results in an increase in image quality. Contact-type transfer rollers are used as secondary and tertiary transfer means, so unlike with a transfer charger (a non-contact type of transfer means), there is no discharge product. A toner image that has been once transferred from an image support onto a recording medium is prevented from being retransferred back onto the image support, and a toner image that has been transferred onto the recording medium by the action of a first transfer member is prevented from being retransferred to the image support when a toner image is transferred onto the recording medium by the action of a second transfer member.

摘要： Disclosed is an image forming apparatus capable of elongating the service life of an intermediate transfer belt and of performing cleaning on the intermediate transfer belt in a satisfactory manner. To remove any residual toner on a second intermediate transfer belt, a cleaning blade is brought into contact with the second intermediate transfer belt, and a voltage is applied to the cleaning blade to thereby remove the residual toner and paper powder. In the case of one-side copying and when no residual toner exists on the second intermediate transfer belt, the cleaning blade is brought into contact with the second intermediate transfer belt to thereby remove paper powder.

摘要： A developing device includes a developer bearing member, a developer supplying conveyer, a developer receiving conveyer and a developer agitating conveyer. The developer supplying conveyer or the developer receiving conveyer has at least one dividing position. The dividing position is a position at which the conveying direction of the developer reverses, and a position which is arranged so that if the dividing position is projected to the developer bearing member along a plane which is perpendicular to the widthwise direction of the developer bearing member, the projected position on the developer bearing member is within an area in which the developer is borne on the developer bearing member.

摘要： An image transferring device for an image forming apparatus and of the type using a belt formed of a dielectric material includes a guide member for guiding a recording medium, which carries a toner image transferred thereto from an image carrier. The guide member is formed with holes spaced from each other in the widthwise direction of the recording medium. A discharging member is received in the holes and has discharge needles. The discharging member is positioned such that the tips of the discharge needles do not contact the recording medium. The guide member includes a center guide portion, opposite end guide portions, and recess portions each connecting the center guide portion and one of the end guide portions. Ribs are formed at stepped portions existing between the center guide portion and the recess portions and between the recess portions and the end guide portions, preventing the holes from catching the recording medium. The guide member guides the recording medium separated from the belt toward a fixing unit while electrostatically attracting the medium.
