A process for preparing an electrophotographic liquid developer based on a resin dispersion, which contains resin particles in a hydrocarbon medium which is highly insulating, is described. In the process, in the presence of a first polymer which is dissolved in the medium and has a polar functional group which is adsorptive towards a second polymer, a monomer having a polar group which is adsorptive towards the first polymer is polymerised, forming a second polymer which has a low solubility in the medium and is substantially in the form of particles. |
