The Effect of Toner Charge in the Cleanerless Printer Using Non-magnetic Development

Abstract

The most important problem in the cleanerless printer using simultaneous development and cleaning is to find a condition in which the influence of the residual toner on the subsequent image can be eliminated. The authors calculated the relations between the major parameters and the memory appearance to obtain the way to optimize these parameters. The results are; (1) There is an optimum range for the development toner charge value. Negative memories tend to appear when the absolute value of the development toner is small, and positive memories when large. (2) The residual toner charge should be as small as possible. (3) The contact-type monocomponent non-magnetic development is suitable for the cleanerless process.
