Dry toner giving good, durable copies without soiling development apparatus

摘要

Dry toner contains a metal oxide and a metallised azo dye. Also claimed is a dry toner, for a development process using a one-component dry developer, which contains a binder resin together with a metal oxide and a metallised azo dye in amounts that prevent toner film formation and scattering of the toner after the development of 10000 copies; and a development process using the toner.
