    • There is provided a charging device having high durability, of which controllability of charged potential of a photoreceptor is hardly impaired even with a some amount of contaminants such as a toner so that control of charged potential of a photoreceptor can be stably carried out to fall in an appropriate range over a long period of time, and moreover which is inexpensive. As a grid electrode, one prepared by forming a composite plated layer composed of three layers of an Sn plated layer, an Sn—Co plated layer and a Ni plated layer is used. More preferably, an upper layer is an Sn plated layer, an intermediate layer is an Sn—Co plated layer and a lower layer is a Ni plated layer.
    • 提供了一种具有高耐久性的充电装置,其中即使有一些污染物如调色剂也难以损害感光体的带电电位的可控性,使得可以稳定地执行感光体的带电电位的控制以落入 长期合适的范围,而且价格便宜。 作为栅电极,使用通过形成由三层Sn镀层,Sn-Co镀层和Ni镀层构成的复合镀层制成的栅电极。 更优选地,上层是Sn镀层,中间层是Sn-Co镀层,下层是Ni镀层。

    • A sheet transport guide includes a torsion coil spring (X). The spring (X) has a first arm (B4) with an end (B5). Through the end (B5), the spring (X) supports a rotation shaft of driven roller (R32) and applies elastic force to the roller (R32). Through the arm (B4) that is curved, the spring (X) guides a sheet toward a rotation roller R31. The spring (X) has a coil portion (B1) and an end (B3) of a second arm (B3) both fixed to a frame of an apparatus body. A plurality of driven rollers (R32) are aligned approximately parallel to a shaft (R31a) of the roller (R31). The rollers (R32) are each provided with the springs (X). A largest elastic force is applied to the roller (R32) at a predetermined reference position, and smaller elastic forces are applied to the other rollers (R32) at positions distant from the reference position.
    • 纸张传送引导件包括扭力螺旋弹簧(X)。 弹簧(X)具有带端部(B 5)的第一臂(B 4)。 通过端部(B 5),弹簧(X)支撑从动辊(R32)的旋转轴并向辊(R32)施加弹性力。 通过弯曲的臂(B 4),弹簧(X)将片材朝向旋转辊R 31引导。弹簧(X)具有线圈部分(B 1)和第二臂的端部(B 3) (B 3)都固定到装置主体的框架上。 多个从动辊(R32)大致平行于辊(R 31)的轴(R 31 a)排列。 辊子(R32)分别设有弹簧(X)。 在预定的基准位置,向辊(R32)施加最大的弹力,并且在远离基准位置的位置向其它的辊(R32)施加较小的弹性力。
