Title: Blasting device, blasting method and developer carrier
Inventor: YAMADA YUSUKE
IPC: G03G21/00
Filed: 1993-06-22
Abstract: PURPOSE:To prevent the deformation of a sleeve due to a blasting processing and to obtain proper surface roughness and surface shape by forming the discharge port of a blast nozzle in a flat shape. CONSTITUTION:When ejection air accelerated by a blasting device passes through an ejection nozzle 3, a negative pressure is generated in a nozzle holder 2, abrasive grains 6 are sucked through an abrasive grain inflow port 4, and the grains are ejected in the air with the ejection air through the blast nozzle 1. Thus, the accelerated abrasive grains 6 collide against the surface of the rotating sleeve 8, then, the surface of the sleeve 8 is roughened. At this time, by forming the discharge port of the nozzle in a flat shape with the aspect ratio of 3:1 to 15:1, most preferably within the ratio of 5:1 to 10:1, the locally concentrated collision of the abrasive grains are prevented, the grains are scattered over a wide extent, so that the deformation of the sleeve 6 is prevented.
