Abstract
A method of deinking an image-bearing member using an organic solvent includes receiving the image-bearing member. The member has thereon a continuous or discontinuous image layer formed of toner particles that do not include colorant, and colorant particles or molecules. The colorant particles or molecules are arranged in a pattern corresponding to the arrangement of the toner particles. The organic solvent is hydrophobic or oliophilic and the colorant is insoluble in the organic solvent. The hydrophobic or oliophilic organic solvent is applied to the image-bearing member, so that a majority of the toner image layer is dissolved off the image-bearing member and the colorant is removed from the image-bearing member. A deinked reflection density of the image-bearing member in a selected test area from which the toner image layer was dissolved is within 0.15 of an unprinted reflection density of the image-bearing member before deinking.
