Electrostatographic developer mixture and imaging process |
(57) Electrostatographic developer mixtures providing substantially improved copy quality
are disclosed. The developer mixtures comprise toner particles substantially all of
which are of a size between a lower size limit of 3 microns and an upper size limit
of between 8 and 15 microns. The carrier particles have a mean size which is not less
than the upper size limit of the toner particles and not greater than 65 microns.
