A liquid developer contains, for example, a nonpolar liquid, thermoplastic resin, optional colorant, and an inorganic filler

Developer compositions and processes

A liquid developer comprised of a nonpolar liquid, resin, optional colorant, and an alkaline earth charge acceptance additive.

A liquid developer comprised of a nonpolar liquid, thermoplastic resin, optional colorant, and an alumina charge acceptance additive.

A liquid developer containing a liquid, colorant, and a wax charge acceptance additive. When free of colorant, the developer is considered colorless or slightly colored.

Imaging apparatuses and processes thereof containing a marking material with a charge acceptance additive of an aluminum complex

Imaging apparatus

Liquid developers and processes thereof

A liquid developer comprised of a nonpolar liquid, resin, colorant, and a charge acceptance component comprised of an aluminum complex of the formulas, or mixtures thereof

A positively charged liquid developer comprised of a nonpolar liquid, thermoplastic resin particles, pigment, a charge director, and a charge control agent comprised of a PEO:PPO, preferably in a solid form.

Liquid developer compositions with copolymers

A liquid developer comprised of a nonpolar liquid, resin, optional colorant, a charge director, and an optional charge control agent, and wherein the charge director is comprised of a mixture of phosphoric acid esters I, II and III, and IV a nonpolar liquid soluble organic aluminum complex of the formulas ##STR1## hydrates thereof or mixtures thereof, wherein R.sub.1 is selected from the group consisting of hydrogen and alkyl, and n represents a number of from about 1 to about 6.

Liquid developer compositions

A process for the reduction of residual image voltage present on an imaging member which comprises contacting the member with a composition comprised of a nonpolar liquid, thermoplastic resin particles, an optional charge adjuvant, charge control additive, carbon black pigment, and a charge director comprised of a nonpolar liquid soluble organic aluminum complex, or mixtures thereof of the formulas ##STR1## wherein R.sub.1 is selected from the group consisting of hydrogen and alkyl, and n represents a number, and wherein said voltage is reduced to from about zero to about 25 volts.
