Abstract

Disclosed in an improved trickle developer system which maintains extended developer life within high volume copiers. In current trickle developer systems, as disclosed in U.S. Patent No. 4,614,165, the wasted carrier beads are removed from a developer housing

TURRET TRICKLE DEVELOPER SYSTEM (CONT'D)

dynamically during a copying operations at the same time that new carrier beads are introduced into the developer housing. A developer housing has an inlet path connected to a replenisher for new carrier beads and an outlet path for wasted carrier beads. Sometimes, the configuration of the inlet path and the outlet path cause immediate discharging of the new carrier beads; especially, when the inlet path and the outlet path are arranged straightforwardly upon the developer auger. The introduced new carrier beads tend to skip across the top of these augers from the inlet path to the outlet path along with the rotation of the augers.

This invention provides a new trickle developer system which avoids the aforementioned problem. The new trickle developer system has a developer housing 2, a drop tube 3 for providing new carrier beads into the developer housing 2 from a replensher supply 4, and a trickle opening 5 for expelling used (dead) carrier beads therethrough, formed on the bottom surface of the developer housing 2. Two baffles 6, 8 are mounted adjacent to the bottom surface of...
