摘要： A fixing device (20) for heating and then fixing an unfused toner image onto a sheet substrate includes a first roller (24) and a second roller (28) spaced apart from the first roller. A third roller (26) is arranged between the first and second rollers. A portion of the third roller is protruded across an imaginary line (38) which contacts with outer peripheries of the first and second rollers on the same side thereof into a region (40) in which the first and second rollers are located. A fourth roller (30) is spaced apart from the third roller beyond the first or second roller. A portion of the fourth roller is also protruded across the imaginary line into the region. A heater (36) is mounted for heating the rollers. The sheet (22) is transported with one surface thereof contacted with the first and second rollers while the other surface thereof is contacted with the third and fourth rollers along a sheet path (42) defined by peripheral portions of the four rollers.

摘要： An image forming apparatus having a charger which applies a voltage of the same polarity as a toner image formed on an intermediate transfer member onto an upstream side of a first transfer portion at which the intermediate transfer member faces an image bearing member, as well as a transfer electrode which applies a bias voltage of an opposite polarity to the toner image onto a downstream side of the first transfer portion. On an upstream side of a second transfer portion at which the toner image formed on the intermediate transfer member is transferred by a transfer roller onto a transfer sheet with respect to a sheet transporting direction, a bias voltage applying device is provided which applies to the transfer sheet a voltage of an opposite polarity to the toner image and greater than a surface potential of the intermediate transfer member at the second transfer portion. At a position facing to the transfer roller through the intermediate transfer member, a voltage of an opposite polarity to the toner image is applied, and a recharger is provided which applies to the intermediate transfer member a voltage of the same polarity as the toner image on an upstream side of the second transfer portion.

摘要： An image forming apparatus for forming an image onto a sheet includes a sheet supporting member; a charger which is positioned in a vicinity of the sheet supporting member; and a device for controlling the charger so that the charger charges a specific portion of the sheet supporting member corresponding to a leading edge portion of the sheet to an electrostatic potential higher than that of a remaining portion of the sheet supporting member. A method of adhering a sheet to a sheet supporting member during an image forming process includes charging a specific portion of the sheet supporting member corresponding to a leading edge portion of the sheet to a first electrostatic potential; charging a remaining portion of the sheet supporting member to a second electrostatic potential that is lower than the first electrostatic potential; and delivering the sheet to the sheet supporting member so that a leading edge portion of the sheet is aligned with the specific portion of the sheet supporting member.

摘要： A throttle opening control device includes a driver for controlling the opening of the throttle during idling and a judgment circuit or an idle switch for determining an idling condition and means for halting driver operation during non-idling intervals. In one embodiment, a sensor detects the throttle opening and supplies the same to a throttle driver by way of a difference circuit which forms a deviation value between the output of the sensor and that of an arithmetic unit whose operation is suspended during non-idling periods.
