Abstract: The invention relates to a process for the preparation of a dry toner powder containing a wax component and formed using a limited coalescence suspension polymerization process. Both conventional and aqueous dispersed waxes may be used to form the toner particles. Likewise, both dry and aqueous dispersed pigments may be used. The resulting toner provides properties desired in the next generation of toners including small uniform particle size as well as desirable anti-blocking and high-temperature anti-offset properties.

Abstract: A method of restoring a used organic photoreceptor which includes a supporting substrate having a photoconductor layer contained on said substrate and an overlaying layer of charge transport material. The photoreceptor is heated to a temperature near or above the glass transition temperature of the charge transport layer for a time sufficient to allow for flowing and/or melting of the top surface of the charge transport layer, and then cooled to room temperature, followed by applying a new layer of charge transport material over the existing charge transport layer.
