摘要 |
<p>Disclosed is a developer composition which in use exhibits improved depletion characteristics and produces copies of high image density. The developer comprises an organic carrier containing a pigment system, a charge control agent, and a "gelatex" which acts as a fixitive and a dispersant. The gelatex comprises a carrier-insoluble vinyl polymer and a multiply-branched, vinyl polymer which physically entraps or entangles the carrier-insoluble polymer and is on the borderline of solubility in the carrier. The gelatex component is present in the carrier as a stable dispersion and is substantially uniformly depleted as multiple copies are produced, resulting in a significantly reduced rate of image density deterioration as multiple copies are produced.</p> |
