Abstract
An electrographic, dry two-component developer composition is disclosed comprising triboelectrically charged carrier particles and oppositely charged toner particles. The toner particles contain, as a binder, an amorphous, random polyester-amide containing amide linkages in the polymer backbone and is derived from certain dicarboxylic acids, compounds containing primary amino groups and compounds containing hydroxyl groups. A process for using the developer composition to form toner image copies of an original is also disclosed.
