Abstract
Non-magnetic single-component process is reported for basic development characteristics. For example, the characteristics of development mechanism using an elastic development roller depends on the resistance of a development roller, the mechanism of the thin toner layer formation by a doctor blade, the toner sticking phenomena on doctor blade and the ghost formation mechanism for the surface potential of the development roller using high resistance development roller.
The uniformity of development ability for halftone images is a significant subject in a contact single-component non-magnetic development system. In digital printing system, it is necessary to hold the development toner uniformity to the photo-conductor for each dot.
We analyze that the mass of the development toner to the photoconductor depends on the diameter of a toner particle using the elastic conductive development roller. And we found the ghost formation is explained by the difference of the toner particle on the surface of the development roller before the development process.
