Abstract

1,211,208. Electrostatographic developers. ADDRESSOGRAPH-MULTIGRAPH CORP. CHARLES BRUNING DIVISION. Oct.31, 1967, No. 57402/67. Divided out of 1,108, 791. Heading G2H. The description is substantially the same as that in original Specification 1, 108, 791 but the claims relate to an electrostatographic developer comprising carrier particles mixed with a toner comprising an infrangible polyamide resin, a colourant and a melt point lowering agent.
