Method for magnetic development of latent electrostatic images
Abstract
Abstract THIS IS A METHOD FOR MAGNETIC DEVELOPMENT OF LATENT ELECTROSTATIC IMAGES WHEREIN DEVELOPMENT CAN BE RAPIDLY STARTED AND STOPPED BY MOVING THE MAGNET MEMBER RELATIVE TO THE ROLL MEMBER FROM A FIRST POSITION IN WHICH DEVELOPMENT OCCURS TO A SECOND POSITION DISPLACING THE MAGNETIC FLUX FIELD AND BRISTLE-LIKE FORMATION OF DEVELOPER MATERIAL AWAY FROM THE IMAGES OF THE PHOTOCONDUCTIVE SURFACE, AND SIMULTANEOUSLY MOVING A PLATE MEMBER FROM A FIRST POSITION SPACED FROM THE ROLL MEMBER DURING DEVELOPMENT TO A SECOND POSITION INTO CLOSE PROXIMITY AND IN OVERLYING RELATIONSHIP WITH THE ROLL MEMBER WHERE THE MAGNETIC MEMBER IS DISPLACED AWAY FROM ITS FIRST POSITION TO ITS SECOND POSITION TO BREAK DOWN ANY BRISTLES OF DEVELOPER MATERIAL AND PREVENT UNWANTED SPURIOUS DEVELOPMENT OF IMAGES.
