Xerox Disclosure Journal
The disclosure relates to those modes of development where a toner comprising a mixture of different size toner particles is used to develop a latent electrostatic image in xero-graphic-type development systems. The toner mixture is commonly designated as a bi-modal size distribution of partic-les, exemplary of which is a toner mixture having particles of about 10 - 15 microns in diameter and particles of about 1 - 5 microns in diameter. The toner mixture may be applied to the image to be developed by a single step process or by a dual development system wherein the developer is a first developer having fine particles and a carrier therefor and a second developer of larger particles and a carrier therefor.
