写真式複写機のクリーニング装置。[Claims for Utility Model Registration] A cleaning device for an electrophotographic copying machine comprising a blade that comes into contact with a photosensitive sheet or transfer sheet having a seam and removes residual toner from the rotating photosensitive sheet or transfer sheet, a movably supporting member; a pressing member that moves the supporting member and presses the blade against the photosensitive sheet surface or the transfer sheet surface; a blade release means that separates the blade from the photosensitive sheet surface or the transfer sheet surface; An electrophotographic method comprising: a detection means that detects when the blade passes a position directly in front of the seam and turns it on; and a control means that activates the blade opening means only for the time when the blade passes the seam after the detection means is turned on. Copy machine cleaning device.
