US 5,176,977 : Nonpolymeric amorphous developer compositions and developing processes
Alexandrovich, Peter S. (Rochester, NY)
Toner and developer compositions incorporating nonpolymeric, homogeneous, amorphous mixtures of compounds as the binder are described. The mixtures comprise at least two nonpolymeric, thermoplastic organic compounds each having at least two linking components joining one multivalent organic nucleus with at least two organic appended groups wherein either the multivalent organic nucleus or at least one of the appended groups in an aromatic group. The mixtures have glass transition temperatures of 50° to 120° C. Methods for developing electrostatic images with the developer compositions are also described.
