Title: Nonuniform scraper load for increase of life of detoner roll
Inventor: DENISU JII GAABASHI
IPC: G03G21/00
Filed: 1995-08-14
Abstract: PROBLEM TO BE SOLVED: To prolong a service life of a scraper blade and to decrease an unwanted wear of a dis-toner roll without decreasing cleaning performance. SOLUTION: A nonuniform load is achieved on dis-toner rolls 114 and 120 and by preventing the wear of terminal parts of the dis-toner rolls, the service life of the dis-toner rolls is prolonged. The nonuniform load of scraper blades 140 and 150 prevents the terminal parts from being worn faster than the intermediate part by nonuniform toner distribution. This is caused since friction force at the terminal parts of the dis-toner rolls 114, and 120 is higher than that of the central part.  In order to prevent the wear of terminal parts, either the scraper blades 140 and 150 or scraper blade holders 145 and 155 disconnect their terminal parts from the dis-toner rolls 114 and 120 at certain angles and without overload at the blade terminal parts where the collection of toner is generally minimized, the desired working load for smoothing the blade terminal parts with enough toner at the central part is enabled.
