Abstract
The aim of this paper is to evaluate the several adaptabilities such as charging, developing and fusing characteristics of sample toners in order to be applied to as the toner of electrophotographic system on the condition of a low temperature. We make four kinds of sample toner having a different pigment addition by using copolymerization method. Then, we encapsulate each toner in order to get sample toners having a same core structure.
Charging amount of sample toners was tested. Flow measurements were carried out sample toners in order to clarify their rheological characteristics. Printability tests of fusing methods were conducted. Also evaluation of image quality was carried out to investigate development characteristics of sample toners using by laser printer.
In spite of micro-encapsulating treatment of sample toner, it was possible to get at least -30μC/g of charging amount. Since, micro-encapsulating treatment was a main reason to decrease the charging amount of sample toners. We found out that it is possible to get the good charging and development characteristic of micro-encapsulated toner for printing test using by laser printer. It is believed that addition ratio of pigments on copolymerization of the sample toner have a strong influence with the variation of the fusing characteristic and oozing behavior of internal resin through capsule wall.
