Drum-photosensitive member and method for manufacturing thereof
Abstract
Abstract A PHOTOSENSITIVE MEMBER HAVING A SMOOTH AND UNIFORM SURFACE PROVIDED BY COATING PHOTOSENSITIVE MATERIAL ON A DRUM IN UNIFORM THICKNESS. THE PRINCIPAL NOVEL METHOD COMPRISES ROTATING A CYLINDER ON ITS HORIZONTAL AXIS, PLACING A KNIFE EDGE OF A BLADE ALONG A CYLINDER GENERATING LINE OUTSIDE OF THE CYLINDER SURFACE, MAINTAINING A PREDETERMINED GAP BETWEEN THE KNIFE EDGE AND THE CYLINDER SURFACE, FACING THE KNIFE EDGE TO THE SURFACE, SUPPLYING A WET PHOTOSENSITIVE MATERIAL IN THE V-SHAPED SECTION FORMED BY THE UPPER SURFACE OF THE BLADE AND THE CYLINDER SURFACE, THEREBY COATING THE CYLINDER SURFACE THROUGH SAID GAP AND THEN TILTING THE BLADE TO BRING THE KNIFE EDGE TO A HIGHER POSITION THAN THE OPPOSITE EDGE OF THE BLADE SO AS TO CAUSE EXCESSIVE WET PHOTOSENSITIVE MATERIAL TO FLOW FROM THE DRUM OVER THE SURFACE OF THE BLADE TO LEAVE A UNIFORM COATING OF PHOTOSENSITIVE MATERIAL ON THE DRUM.
