Title: Developing device
Inventor: IGAWA SHOJI
IPC: G03G15/08
Filed: 1988-12-23
Abstract: PURPOSE:To keep the concentration of toner proper until the toner is nearly exhausted by lowering collection bias based on the quantity of the toner in a toner hopper and making the potential difference between the collection bias and developing bias small. CONSTITUTION:The regular potential difference between the collection bias and the developing bias is made small by lowering the collection bias based on the output of a detection means 21 which detects the quantity of the toner in the toner hopper 4. A constant-voltage signal R1 and a collection bias control signal (a pulse signal) R2 are outputted to the power source 23 of the collection bias from a CPU 20 and the output is turned on or off corresponding to the duty ratio of the collection bias control signal R2. Therefore, the force that electrostatically charged toner is electrically attracted to a toner supplying roller can be made weak by making the potential difference between the developing bias and the collection bias small. Thus, the quantity of the toner on the circumferential surface of a developing sleeve is continuously kept constant by decreasing the collecting quantity of the toner along with the decrease of the supplying quantity of the toner.
