摘要： An intermediate transfer type image forming apparatus is provided, in which a secondary transfer unit includes a secondary transfer member having a contact transfer member disposed in contact with at least the surface of an intermediate transfer medium, a bias applying unit for applying a transfer bias to transfer a toner image on the intermediate transfer medium through the secondary transfer member to a transfer medium and an inverse transfer bias having the opposite polarity to the transfer bias, and a bias switching unit for switching the applied bias of the bias applying unit so that the transfer bias is applied to an image transfer area on the intermediate transfer medium and the inverse transfer bias is applied to an image non-transfer area on the intermediate transfer medium. The apparatus is also equipped with a disturbing member for disturbing (scraping out, sweeping off or the like) toner adhering to the contact transfer member.

摘要： The invention provides a double-faced image formation system that prevents transfer and adhesion of a lubricant to an image retaining conveyer and an intermediate transfer part. The system is provided with, on a return path for reversing and conveying a sheet having toner images fixed on one side thereof, a front face electrifying unit and a rear face electrifying unit. Oil adhered on the rear face of the sheet in a fixation unit by the rear face electrifying unit is electrified to a negative polarity, and the oil adhered on the rear face is made impossible to transfer to an intermediate transfer belt. The oil adhered on the front face of the sheet in the fixation unit by the front face electrifying unit is electrified to a positive polarity, and the oil adhered on the front face is made impossible to transfer to a secondary transfer conveyance belt.

摘要： Image formation condition is available, which hardly causes imperfections of the image quality. A full-color image formation system selects plural secondary transfer conditions in a secondary transfer unit within a specific range, forms test charts according to each of the secondary transfer conditions selected, and prints them out. A user checks by viewing the test charts printed on each recording sheet, and selects a page number of the sheet where the user evaluated an image quality as the best; and the image formation system sets the secondary transfer condition for the sheet as a standard secondary transfer condition thereafter.

摘要： The present invention enables registration adjustments during actual use of an image forming apparatus. A test pattern is formed on a sheet in a full-color image forming apparatus and the test pattern formed on the sheet is read in an image read unit. From the result of reading the test pattern, misregistrations of vertical and horizontal scaling factors, parallelism, squareness, skew, side registration, and lead registration in the test pattern are determined, and mounting positions, drive timings, drive speeds, and the like of constituent members are adjusted.

摘要： There is provided an image forming apparatus capable of finely cleaning a transfer roll at all times by regulating the relation between a mechanical adhesion force of toner to the surface of the transfer roll and a mechanical adhesion force of toner to the surface of an image carrier with which the transfer roll comes in press contact. At the time of cleaning the transfer roll, both the electrostatic adhesion force and the mechanical adhesion force of charged colorant to the surface of the belt-like image carrier are set larger than the electrostatic adhesion force and the mechanical adhesion force of charged colorant to the surface of the transfer roll.
