Abstract:
A non-contact, single-component developing system comprising:a photoreceptor capable of having an electrostatic latent image recorded thereon; and a toner support member disposed in opposing relationship with the photoreceptor with a gap therebetween defining a developing region, the toner support member adapted to carry a toner thereon to the developing region; wherein the developing region is without AC voltage and wherein the toner comprises toner mixed with large and small extraparticulate particles, a weight concentration of small extraparticlate particles resulting in a first surface coverage of the toner in a range of about 50 to 150 percent and a weight concentration of large extraparticulate particles resulting in a second surface coverage of the toner in a range of about 5 to 50 percent.
