摘要： An image forming apparatus of the present invention includes a pair of support plates supporting the rotary shaft of a photoconductive drum at axially opposite ends of the drum. One of the support plates is openable away from the body of the apparatus and loaded with a contact forming member including a current feed path for feeding a current from a high-tension power supply for charging to a charge roller, a wiring forming a current return path that allows a current to flow from the photoconductive drum to the ground of the power supply, and a plurality of contacts where the wiring and drum contact each other. A current flowing through the current return path is sensed to execute feedback control to the output of the high-tension power supply.

摘要： A sheet feeding apparatus includes a fixing device to fix a toner image by heat, a discharging tray to accommodating a sheet fixed toner image at the fixing device, a sheet feeding device including a sheet discharging roller to discharge the sheet and positioned downstream of the fixing device, and a sheet cooling device to cool the sheet fixed toner image. The sheet cooling device is located along the direction in which the sheets are stacked and is close to the sheet discharging device. Blocking from adhesion of sheets to each other by melting toner may be prevented by cooling the discharged sheet efficiently after the fixing.

摘要： An image forming apparatus includes an imaging unit for black and imaging units for other colors, a writing unit for black and a writing unit for other colors, a first heater corresponding to the imaging unit and the writing unit for black color, and a second heater corresponding to the imaging units and the writing unit for other colors. Turning ON/OFF of each of the first heater and the second heater are controlled separately. Thus, the first heater can be ON while the second heater is OFF.
