    摘要: A transfer roller is spaced away from the outer surface of a photosensitive drum by a specified distance to prevent the abrasion and damage of the photosensitive drum by the contact of the transfer roller and the photosensitive drum. The transfer roller not in contact with the photosensitive drum can be formed to have a sufficient hardness without damaging the outer surface of the photosensitive drum. Further, since the transfer roller has a sufficient hardness, cleaning blades can be held in without damaging the transfer roller with a sufficiently large force without damaging the transfer roller, thereby securely scraping off toner and the line adhered to the transfer roller and preventing the rear surface of a transfer sheet from being smeared.

    摘要: Image forming apparatus including a paper return device for feeding a sheet of paper ejected from a paper output port opening in a main body of the apparatus to its outside back to a paper feeding port also opening in the main body to its outside. For double-sided copying operation, the sheet of paper ejected from the paper output port carrying an image on one side only is returned to the paper feeding port and fed again to an image former from the paper feeding port so that it is not necessary to provide a dedicated paper path for re-feeding the paper. The apparatus includes a paper sensor which senses the paper inserted into the paper feeding port and outputs a paper sensing signal, a discriminator for judging whether the paper return device is in an operating condition, and a paper feed controller which controls a driver for driving a paper feeder such that the paper feeder initiates a paper feed operation when the paper sensing signal is output while the paper return device is in its operating condition.

    摘要: In an image forming apparatus which uses a hollow space between an image reading section provided in an upper part of the apparatus and an image forming section provided in a lower part of the apparatus as a paper output space, the hollow space is used also as a space for temporarily holding a sheet of paper during a switchback operation. This arrangement helps prevent physical contact between the paper and the body of an operator or other objects and makes it easier to deal with a paper jam which is likely to occur during the switchback operation.

    摘要: A document feeder to be mounted atop an image reading device having a stationary optical system disposed under a contact glass. The document feeder includes a document original plate for holding thereon document originals, a document original feeding mechanism for feeding a document original from the document original plate onto a contact glass, a document original transporting mechanism for transporting the document original fed by the document original feeding mechanism along the upper surface of the contact glass, a document original discharging mechanism for discharging the document original transported by the document original transporting mechanism, and a document original discharge plate for receiving the document original discharged by the document original discharging mechanism. The document original feeding mechanism, the document original transporting mechanism and the document original discharging mechanism are integrally supported in a unit body to constitute a single unit.

    摘要: An image forming apparatus according to the present invention comprises three units, that is, an image forming unit 40, a fixing unit 60, and a transfer unit 50. The three units are mounted on a main frame 10 with a positional relationship upon being positioned therebetween. The image forming unit 40 is fixed to a predetermined position with respect to the main frame 10. Further, the main frame 10 comprises a positioning pin 14 arranged in a predetermined positional relationship with the image forming unit 40. The fixing unit 60 and the transfer unit 50 are positioned upon being engaged with the positioning pin 14. Consequently, there is no shift in position among the image forming unit 40, the transfer unit 50, and the fixing unit 60. The three units can be correctly mounted on the main frame 10.
