Abstract

With commercial toners used in xerographic development, there is a suppression of background during the transfer step be-cause the mass transfer efficiency in areas of low image density is about 45% compared to about 75 - 90% in areas of high density. This can be overcome by using a toner compri-sing a mixture of different size toner particles, that is, a bi-modal size distribution.
