摘要： A positional deviation correction pattern includes a first and second pattern image portions adjacent in a sub-scanning direction at the same position in a main-scanning direction, with the same width in the main-scanning direction. Each image portion includes a first side extending in the sub-scanning direction, a second side continuing from one end of the first side and extending in a direction intersecting the sub-scanning direction, and a third side continuing from the other end and extending in a direction intersecting both the sub-scanning direction and the second side. The second sides have the same inclination angle to a virtual line parallel to the main-scanning direction. The third sides have the same inclination angle to the virtual line. A length of one image portion in the sub-scanning direction gradually increases from one end to the other end in the main-scanning direction, a length of the other image portion gradually decreases.

摘要： A multicolor image forming method in which a plurality of latent images are sequentially formed and developed on an image carrier on top of each other on the image carrier. The second and any successive color toners are developed in a non-contact manner. A developed image on a photoconductive element is prevented from being contaminated by subsequent developing stages and toner on the photoconductive element is prevented from contaminating the developer in the subsequent developing stages by reducing the amount of toner which improperly flies between the photoconductive element and the developing stages. Such a prevention of the flight of toner can be accomplished by keeping the potential of the toner on the photoconductive element within a predetermined threshold of the voltage of the toner in the subsequent developing stages. Also, properties of the various toners can reduce the improper flight of the toner such as by controlling the relative amounts of hydrophobic SiO.sub.2 within the toners, controlling the average volume particle size of the toners, controlling the average volume particle size and the average number particle size, and controlling the voltage difference between the toner on the photoconductive element and the toner in the subsequent developing stage(s).
摘要翻译：一种多色图像形成方法，其中在图像载体上在多个潜像依次形成并显影在图像载体上。第二种和任何连续的彩色调色剂以非接触的方式开发。防止光电导元件上显影的图像被后续显影阶段污染，并且防止光电导元件上的调色剂通过减少在光电导元件和显影级之间不正确地飞行的调色剂的量而在后续显影阶段污染显影剂。通过将调色剂在光电导元件上的电位保持在随后显影阶段的调色剂电压的预定阈值内，可以实现这种防止调色剂飞行的情况。此外，各种调色剂的性质可以通过控制调色剂中的疏水SiO 2的相对量来控制调色剂的平均体积粒径，控制平均体积粒径和平均粒子数并且控制感光元件上的调色剂与后续显影阶段中的调色剂之间的电压差。
