Abstract
A cleaning roller includes a shaft and an elastic body. The shaft extends in an axial direction where a center axis of the shaft extends. The shaft defines a radial direction and has a circumferential surface. The elastic body is helically wound about the shaft and defines a helical direction. The elastic body has a widthwise dimension in a widthwise direction orthogonal to the helical direction and to the radial direction. The elastic body has a base end portion extending in the helical direction and a distal end portion extending in the helical direction. The base end portion is in contact with the circumferential surface and fixed thereto. The distal end portion has a sharp edge and is positioned farthest from the circumferential surface in the radial direction. The widthwise dimension is gradually reduced from the base end portion to the distal end portion in the radial direction.
