An imaging process which comprises (1) charging an imaging member in an imaging apparatus; (2) creating on the member a latent image comprising areas of high, intermediate, and low potential; (3) developing the low areas of potential with a first developer comprising carrier particles and a first negatively charged toner comprised of resin, the magenta pigment 2,9-dimethyl quinacridone, a charge additive, or a mixture of charge additives, and surface additives; (4) developing the high areas of potential with a second developer comprising carrier particles and a second black toner comprised of resin, pigment, and a charge enhancing additive that enables a positively charged toner; (5) transferring the resulting developed image to a substrate; and (6) fixing the image thereto.

Magenta toner and imaging processes

An imaging process which comprises (1) charging an imaging member in an imaging apparatus; (2) creating on the member a latent image comprising areas of high, intermediate, and low potential; (3) developing the low areas of potential with a first developer comprising carrier, and a first negatively charged toner comprised of resin, the cyan pigment Pigment Blue 15:3, Color Index number 74160:3, CAS Number 147-14-8, a mixture of charge enhancing additives, and surface additives; (4) developing the high areas of potential with a second developer comprising carrier and a second black toner comprised of resin, pigment, and a charge enhancing additive that enables a positively charged toner; (5) transferring the resulting developed image to a substrate; and (6) fixing the image thereto.
