摘要： A transfer station for toner transfer in an electrophotographic imaging device includes an endless transfer belt transported about an endless path through the imaging device, a transfer roll adjacent one surface of the transfer belt, and a backup roll adjacent an opposite surface of the transfer belt opposite from the transfer roll such that the transfer roll and backup roll form a transfer nip effecting transfer of toner. For the purpose of improved overtransfer performance, an outer layer of a thin polymer coating is applied to at least one of the transfer belt and the rolls so as to be located within the transfer nip with transfer of toner. The polymer layer has a thickness from about 5 μm to about 200 μm, surface resistivity from about 1E08 to about 1E12 Ohm/cm and breakdown strength greater than 500 V.

摘要： Image transfer quality in an electrophotographic image forming device is improved by preconditioning a media sheet prior to transferring a toner image thereto at an image transfer station. The media sheet is preconditioned by applying a static charge to it. In a color DTM type device, the charge reduces the transfer voltages required at downstream image transfer stations to account for charge accumulated on the media sheet as a result of the image transfer process at upstream image transfer stations. The charge may be applied to the media sheet at a media sheet preconditioning element positioned upstream of an image transfer station. Alternatively, an initial charge may be applied to the media sheet at an image transfer station, without transferring a toner image to the sheet, and returning the sheet via a duplex path to positioned upstream of an image transfer station prior to an image transfer operation.

摘要： The present application is directed to devices and methods for moving media sheets in an image forming device. In one embodiment, a contact member includes a contact roller that contacts a top-most media sheet in a stack of media sheets positioned on a support surface in an input area of the image forming device. A hub extends outward from an axial side of the contact roller. The hub includes a smaller length than the contact roller, forming a gap between the hub and the top-most media sheet when the contact roller is in contact with the top-most media sheet. The hub prevents or reduces transverse buckling of the top-most media sheet when it is moved from the stack of media sheets.
