摘要： In order to output a print with high gloss uniformity, a transparent toner is consumed in a large amount. For that reason, when a constitution of a color developing device and a constitution of a transparent developing device are made substantially identical, a charge amount of the transparent toner is lowered with continuous image formation. In a state in which the transparent toner is not sufficiently charged, an electrostatic image formed on a photosensitive member cannot be sufficiently developed with the toner.Therefore, a triboelectric chargeability of the transparent toner by a developer carrying member provided in the transparent developing device is made higher than a triboelectric chargeability of a color toner by a developer carrying member provided in the color developing device.

摘要翻译： 为了输出具有高光泽均匀性的印刷品，大量消耗透明调色剂。 为此，当彩色显影装置的结构和透明显影装置的结构基本相同时，透明调色剂的电荷量随着连续的图像形成而降低。 在透明调色剂未充分充电的状态下，形成在感光构件上的静电图像不能用调色剂充分显影。 因此，通过设置在透明显影装置中的显影剂承载构件的透明调色剂的摩擦带电性高于彩色显影装置中设置的显影剂承载构件的彩色调色剂的摩擦带电性。
