摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of obtaining stable separation of a recording material over time, and reducing a portion of an image affected by toner scattering or irregular transfer even when forming an image at a leading edge area of the recording material. SOLUTION: An evenly charged surface of a photoreceptor drum is discharged by a PTL serving as a discharging means, and the surface potential of the photoreceptor drum after the PTL discharging is detected by a potential sensor. If a detection result obtained by the potential sensor 30 is 200 V or less, the process terminates without changing a PTL drive voltage and a leading edge transfer current. By contrast, if a detection result obtained by the potential sensor 30 is 200 V or greater, The PTL drive voltage is controlled so that the detection result obtained by the potential sensor is less than 200 V. When a detection result obtained by the potential sensor is not less than 200 V despite the control of the PTL drive voltage, a leading edge transfer bias is set to 5 [μA].

摘要： An imaging system incorporating the invention includes a movable photoconductive surface, and an electrostatic system for repetitively charging the photoconductive surface to a first charge potential. A laser system selectively discharges the photoconductive surface to a second charge potential in accordance with image signals. A color toner supply provides color toner to the photoconductive surface, the color toner exhibiting a charge state that is attracted by the second charge potential and is repelled by the first charge potential. An adhesive toner supply provides adhesive toner to the photoconductive surface, the adhesive toner exhibiting an opposite sense charge state to the color toner. The adhesive toner is attracted by the first charge potential and is repelled by the second charge potential. A controller causes the color toner to be applied to the photoconductive surface and the entire photoconductive surface is recharged. Thereafter the laser system discharges non-imaged areas of the photoconductive surface to a charge potential that repels the adhesive toner. Then, the adhesive toner is applied to imaged areas which remain at the first charge potential. During a subsequent image transfer the adhesive toner aids in complete image transfer.
