The invention relates to an electrophoretic ink including particles that may have a negative charge, dispersed in a non-polar organic solvent. Said ink is characterized in that it includes a trialkylamine charge-control agent, selected from the following charge-control agents: tributylamine, triisobutylamine, tripentylamine, trihexylamine, tri(2-ethylhexyl)amine, trioctylamine, triisooctylamine, tridodecylamine, triisododecylamine; and in that the particles have a hydrophobic surface and an isoelectric point (IEP) or a point of zero charge (PZC) that is lower than the pKa of the charge-control agent.
