To provide a cleaning member for an image forming apparatus which suppresses the occurrence of distortion of an elastic layer after storage. For example, in a roll-shaped cleaning member provided with a core body 100A and an elastic layer 100B as core bodies, the elastic layer 100B includes a strip-shaped elastic member (hereinafter referred to as a strip 100C) as a core body. It is spirally wound around the surface of 100A. Specifically, the elastic layer 100B is disposed, for example, from one end of the core body 100A to the other end, with the axis of the core body 100A being a spiral axis, and in a state where the strip 100C is wound in a spiral shape with an interval. Let The elastic layer 100B has a thickness t (mm) at the center in the spiral width direction of the elastic layer in a state of being wound around the outer peripheral surface of the core body 100A, and the width of the strip 100C before being wound around the outer peripheral surface of the core body 100A. Conditional expression (A1): 0.7 <t / T <1.0 is satisfied, where T (mm) is the thickness at the center in the direction. [Selection] Figure 3 |
