PROBLEM TO BE SOLVED: To provide a charging device capable of suppressing the occurrence of distortion of an elastic layer of a cleaning member after storage.SOLUTION: There is provided a cleaning member which comprises: for example, a charging member for charging a body to be charged; a core body 100A as a core body; and an elastic layer 100B. The elastic layer 100B is spirally wound by a strip-like elastic member (hereinafter referred to as a strip 100C) on the surface of the core body 100A. Specifically, the elastic layer 100B is arranged, for example, in a state where the strip 100C is spirally wound around with a given interval using the axis of the core body 100A as a spiral axis from one end to the other end of the core body 100A. In addition, if the thickness at the central part in the spiral direction of the elastic layer in a state of being wound on the outer peripheral surface of the core body 100A is defined as t (mm) and the thickness of the central part in the width direction of strip 100C before being wound on the outer peripheral surface of the core body 100A is defined as T (mm), the elastic layer 100B satisfies the conditional expression, (A1):0.7<t/T<1.0. |
