PROBLEM TO BE SOLVED: To provide a method for manufacturing recycled pulp fibers having a low hemicellulose content rate， and suitable as a cellulose raw material. SOLUTION: There is provided a method for manufacturing recycled pulp fibers from pulp fibers contained in a used sanitary material. The method includes a recycled pulp fiber formation step for forming recycled pulp fibers having a hemicellulose content rate less than 8.0 mass% from pulp fibers by supplying ozone-containing gas into a treatment tank containing process liquid including pulp fiber inclusions containing pulp fibers derived from the used sanitary material.
