Electrophotographic ink compositions

A method of liquid electrophotographic printing comprising:

• combining a charging composition with a liquid electrophotographic ink composition to form a print ready liquid electrophotographic ink composition;
• and
• liquid electrophotographically printing the print ready liquid electrophotographic ink composition;
• wherein the charging composition comprises:
• a lecithin;
• a sulfonic acid amine salt;
• and
• a metal salt of a sulfonic acid;
• and
• wherein the liquid electrophotographic ink composition comprises:
• chargeable particles comprising a pigment, a thermoplastic resin and a charge director in a carrier liquid;
• wherein the charge director consists of a metal salt of a sulfonic acid.
