Abstract

1477483 Electrographic developers ADDRESSOGRAPH MULTIGRAPH CORP 16 May 1974 [23 May 1973] 21912/74 Heading G2H The fatigue resistant properties of a dry developer comprising a mixture of carrier particles and pigmented thermoplastic resin toner particles are enhanced by including in the mixture 0.005 to 1.0 wt. per cent, based on the weight of the carrier particles of MoS 2 , TiS 2 , WS 2 or graphite. The carrier particles may be formed of ferro-magnetic materials such as Fe, Ni, Co or their alloys, or ferrite compounds, or of non-magnetic materials such as glass beads.
