PROBLEM TO BE SOLVED: To prevent resin parts from being degraded when a paper label is removed by spraying dry ice particles onto the paper label stuck on the resin parts. SOLUTION: The dry ice particles are sprayed onto the paper label 22 stuck on a flank 20A of a cover 20, which is attached to a supporting frame of a photoreceptor unit and is made of ABS resin, to remove the paper label 22 from the cover 20. At this time, degradation of the cover 20 can be prevented by limiting spraying pressure P of the dry ice particles to 0.30 to 1.00 MPa, spraying distance H to≤0.06m and spraying time T to <8.0s.
