It is pressed against the portion of the substrate 610 located around the planar electrode 620.
As a result, the space located around the planar electrode 620 is a space located closer to the planar electrode 620 (space indicated by reference numeral 11C in the figure) and a space located on the side away from the planar electrode 620 (the space indicated by reference numeral 11C in the figure). It is partitioned from the space indicated by reference numeral 11D in the figure).

In this case, adhesion to the planar electrode 620 is less likely to occur as compared with the case where the first plate-shaped portion 931 and the second plate-shaped portion 932 are not provided.
Toner or the like may be floating in the image forming apparatus 1, and if the first plate-shaped portion 931 and the second plate-shaped portion 932 are provided as in the present embodiment, the toner is surfaced.

More specifically, in this configuration example, the metal piece 828 is not linear, and the metal piece 828 is provided with a shape that makes the position on the root side and the position on the tip side of the metal piece 828 different from each other. The position of the portion 829 and the position of the protruding portion 937 are different from each other.

In this configuration example, the protrusion 937 does not pass over the planar electrode 620, and the wear of the planar electrode 620 is reduced.
In other words, in this configuration example, the protrusion 937 is located at a position off the movement path of the contact portion 829, and the protrusion 937 does not pass over the planar electrode 620.

Further, in this configuration example, the substrate 610 of the power-fed member 600 is made of a non-conductive material.

Here, also in this configuration example, the interlocking portion 930 is formed of a resin material and is formed softer than the contact portion 829. As a result, in the present embodiment, the guide portion 49 with which the interlocking portion 930 comes into contact is less likely to be worn.
The interlocking unit 930 is not essential and may be omitted. More specifically, in the present embodiment, the interlocking portion 930 is formed of a resin material and is a separate component from the metal piece 828, but the portion of this separate component may be omitted without being provided. In this case, the tip of the metal piece 828 is guided by the guide portion 49.
In this configuration example, the portion of the metal piece 828 other than the contact portion 829 does not come into contact with the substrate 610, so that unintentional energization between the tip portion of the metal piece 828 and the substrate 610 is prevented even if the above-mentioned separate parts are not provided.
