An object of the present disclosure is to provide a method of producing an opened fiber bundle at high speed and in a space-saving manner. The method is as follows. A method of continuously producing an opened fiber bundle for a cleaning member, comprising the steps of (a) providing (i) first nip rolls, (ii) second nip rolls, (iii) third nip rolls, and (iv) an opening facilitator; (a) conveying a fiber bundle using the first nip rolls and the second nip rolls to apply a tensile force to the fiber bundle, the fiber bundle being pushed onto the upstream portion and the edge of the opening facilitator while conveying; and (a) conveying the fiber bundle using the second nip rolls and the third nip rolls to relax the fiber bundle, thereby forming a belt-shaped fiber bundle.
