    • A charging device capable of improvement in charging uniformity on an object to be charged, an image forming apparatus having the charging device, and a discharge electrode forming method are provided. The charging device has a discharge electrode which is disposed in an interior space of a shield case, has a plurality of projections aligned in one direction from which a stream of ions is generated, the projections each being so constituted that a widthwise direction thereof makes a predetermined angle with respect to a first imaginary plane including an arrangement direction C of the projections on a second imaginary plane which includes the arrangement direction C and is perpendicular to the first imaginary plane in order that streams of ions generated from the projections that are arranged adjacent to each other in a lengthwise direction of the shield case can overlap each other when viewed in a widthwise direction of the shield case.
    • 提供一种能够改善被充电物体的充电均匀性的充电装置,具有充电装置的图像形成装置和放电电极形成方法。 充电装置具有设置在屏蔽壳体的内部空间中的放电电极,在从其产生离子流的一个方向上排列有多个突起,所述突起各自构成为使其宽度方向为 包括相对于第一假想平面的预定角度,该第一假想平面包括在包括排列方向C并且垂直于第一假想平面的第二假想平面上的突起的排列方向C,以便从邻近布置的突起产生的离子流 在屏蔽壳体的宽度方向上观察时,能够在屏蔽壳体的长度方向上彼此重叠。
