A developer mixture having improved flow properties is pro-vided by blending finely-divided toner particles with at least about 95 percent by weight of carrier particles having an average particle size of between about 30 and 1,000 microns. The carrier particles are a mixture wherein from between about 99 percent and about 90 percent by weight of the carrier par-ticles have an average diameter of approximately the same size, and wherein from about 1 percent to about 10 percent by weight of the carrier particles have an average diameter sub-stantially larger than the other carrier particles.
