ABSTRACT:
An image forming apparatus includes: a first electrode including a spring portion extending in an axial direction and an annular contact portion extending from a first side in the axial direction; a first frame including a through hole, through which the annular contact portion protrudes; and a second frame, which is relatively movable to the first frame along an elongated direction of the annular contact portion at a further extension of the first side in the axial direction, and which includes a second electrode electrically connectable with the annular contact portion. A diameter of the annular contact portion is larger than that of the spring portion. The first frame includes a lock portion that locks the annular contact portion to place a center of the annular contact portion on a second side, which is opposite to the first side, in the axial direction from an end of the through hole.
