Analysis of Toner Behavior in Developing Gap of Mono Component Developing System

Abstract

The behavior of the toner in the mono-component non-contact development was analyzed using the measuring device originally developed by us. As a result, it was clarified that the toner movement in the development gap is based on the space charge limited current, and a development equilibrium model was constructed. Specifically, it has been shown that in the mono-component non-contact development, there are two equilibrium states of the toner transfer amount, and the development amount is determined. One is determined in an equilibrium state where the potential is zero. The other is determined in an equilibrium state where the electric potential does not become zero due to the effect of toner adhesion. It was confirmed that the former occurred in the high contrast region and the latter occurred in the low contrast region.

In this paper, we report our efforts from the results of basic experiments to model creation and formulation.
