Large particle toner printing method

A printing method comprising the steps of:

• mixing first toner particles with carrier particles to form a first developer having a determined ratio of toner and carrier and having a charge at a first charge-to-mass ratio;
• exposing the first developer to a first electrostatic field caused by a first difference in potential so as to urge the toner to transfer across a first transfer distance;
• mixing second toner particles with carrier particles to form a second developer having a determined ratio of second toner particles and carrier and having a charge at a second charge-to-mass ratio;
• exposing the first developer to a second electrostatic field caused by a second difference in potential so as to urge the toner to transfer across a second transfer distance.
• wherein the second toner particles have a volume average weighted diameter of greater than 20 um, the first toner particles have a volume weighted average diameter between about 3 um to 9 um and wherein the second transfer distance is greater than the first transfer distance but the second toner particles are treated with a charge control agent and a particulate addenda allowing the transfer of the second toner particles with the second electrostatic field being less than the first electrostatic field.
