Abstract

PURPOSE: To enable development of images with a variety of width with only one kind of developing apparatus, by changing the thickness of magnetic toner carried onto a magnetic sleeve with doctor blades provided on subplates independently operated by cams.
CONSTITUTION: When setting shaft 11 is rotated to independently rotare cam 12 or 12', subplate 13 or 13' moves together with doctor blade 5 or 5' prepared in one body with subplate 13 or 13' and the width of a toner layer to be formed on magnet sleeve 3, thus permitting a development width to be changed in accordance with the width of images 6 to be recorded and thereby images of a variety of width to be developed using only one kind of developing apparatus.
