Abstract
Full process color imaging using black, magenta, cyan and yellow toners. A photoreceptor is utilized which is responsive to two beams of a dual wavelength laser diode exposure device or of Light Emitting Diode (LED) exposure devices operating at two different wavelengths. One of the light beams emitted by the exposure device is utilized to imagewise discharge the photoreceptor through the magenta and yellow toners while the other beam is used to imagewise expose the photoreceptor through the cyan toner.
