ABSTRACT:
A couple of copy sheet stripping members are provided for scraping away a copy sheet adhered strictly to one of two rollers which are driven to fix images of an original document on the copy sheet in pressure engagement. At least one of the copy sheet stripping members is secured removably from the roller while the copy sheet is not transferred out of the rollers. The copy sheet stripping member becomes pressed against the roller in accordance with the transferring of the copy sheet which is detected by a sensing means. The copy sheet stripping member is free of residue attached on the roller because the period of time where the engagement between the roller and the copy sheet stripping member is kept is very short. The other copy sheet stripping member can be further disposed to assure both the scrape of the copy sheet and the removal of the residue on the roller, the copy sheet stripping member being continuously pressed against the roller.
