摘要： An apparatus for forming a multi-color is disclosed which includes a controller that performs an anti reverse-transfer control such that a surface potential of a previously-formed separated-developer-image subset of a plurality of single-color separated-developer-images which has been previously transferred onto an image transferred medium is reduced, prior to a subsequent transfer in which a remainder of the plurality of separated-developer-images is transferred onto the image transferred medium after a previous transfer of the previously-formed separated developer-image subset onto the image transferred medium, to thereby prevent a reverse transfer of a part of a developer material on the image transferred medium from the image transferred medium onto a photoconductor at the subsequent transfer.

摘要： The pressure between a developing roller and a photosensitive drum is set to 0.24 MPa. Because the pressure is smaller than 0.31 MPa, if the potential difference ΔV between the non-image forming part on the photosensitive drum and the electrically-charged polymer toner on the surface of the developing roller is at the preset proper voltage (300 volts), pressure fogging will be prevented. Because the pressure is 0.24 MPa or less, even if the potential difference varies within the range of 200 volts to 400 volts that occurs in practice, pressure fogging will be prevented. By resetting the pressure to 0.22 MPa, even if the potential difference ΔV varies in a wider voltage range of 100 to 400 volts, pressure fogging will be prevented. In this way, by setting the pressure between the developing roller and the photosensitive drum appropriately, pressure fogging can be prevented even when using the opposite-direction developing method and polymer toner.
摘要翻译：显影辊和感光鼓之间的压力设定为0.24MPa。由于压力小于0.31MPa，如果感光鼓上的非图像形成部分和显影辊表面上带电的聚合物调色剂之间的电位差DeltaV处于预设的适当电压（300伏），防止压力起雾。由于压力为0.24MPa以下，所以即使电位差在实际发生的200〜400V的范围内变化，也可防止压力起雾。通过将压力重置为0.22MPa，即使电位差DeltaV在较宽的100〜400V的电压范围内变化，也可防止压力起雾。以这种方式，通过适当地设置显影辊和感光鼓之间的压力，即使使用相反方向的显影方法和聚合物调色剂也可以防止压力起雾。
