摘要： A process for generating two-color images comprising: (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) providing an electrode having a potential within about 100 volts of that of the intermediate potential, enabling generation of an electric field and a developement zone between the imaging member and the electrode; and (4) developing the latent image by introducing into the development zone a liquid developer composition containing first toner particles of one color and second toner particles of another color, the particles being dispersed in a liquid medium, wherein the second toner particles are attached to the high potential and the first toner particles are attracted to the low potential. Another embodiment of the invention resides in a process for generating two-color images, comprising: (1) creating on an imaging member in an imaging apparatus a latent image comprising areas of positive, negative, and substantially no potential; (2) providing an electrode having a potential within about 100 volts of that of the area of substantially no potential, enabling the generation of an electric field and a development zone between the electrode and the imaging member; and (3) developing the latent image by introducing into the development zone a liquid developer composition containing first toner particles of one color and second toner particles of another color, the particles being dispersed in a liquid medium, wherein the second toner particles are attracted to the positive potential and the first toner particles are attracted to the negative potential.
