Method for development of electrostatic images
Abstract
Abstract DEVELOPER IS FED INTO A CAVITY FASTER THAN IT IS DISCHARGED CREATING A DEVELOPER ACCUMULATION IN THE CAVITY FORMING A SOFT, AGITATED DEVELOPMENT MEDIUM. IN PREFERRED EMBODIMENTS, TWO MAGNETIC BRUSHED ARE ARRANGED TO CREATE THE ACCUMULATION IN THE FORM OF A GENTLY TUMBLING ROLLBACK FROM THE CONTACTING OF ONE OF THE BRUSHES WITH THE IMAGE-BEARING SURFACE. IN THE PREFERRED EMBODIMENTS, THE ACCUMULATION IS ACCENTUATED BY ADJUSTING THE SPACING BETWEEN THE BRUSHES AND THE IMAGE-BEARING SURFACE, ADJUSTING THE PERIPHERAL SPEED OF THE BRUSHES AND CONTROLLING THE DIRECTION OF MOVEMENT OF THE IMAGE-BEARING SURFACE RELATIVE TO THE MOVEMENT OF THE BRUSHES. CARRIER CARRYOUT IS REDUCED BY DIRECTING A STRONG MAGNETIC FLUX AT THE ROLLBACK AREA AND BY PROVIDING AN AUXILIARY CARRIER SCAVENGING MECHANISM.
