LARGE PARTICLE TONER PRINTING METHOD
摘要:
Printing methods are provided. In accordance with one aspect, a first toner image is formed with a first toner particles having a median volume weighted diameter between about 3 um and 9 um and having a first charge-to-mass ratio and, a second toner image is formed with second toner particles having a median volume weighted diameter greater than about 20 um and having a charge-to-mass ratio that is between ⅓ to ½ of the first charge-to-mass ratio times the ratio of the volume weighted average diameter of the first toner to the volume weighted average diameter of the second toner. The first toner image is transferred to a receiver using a first electrostatic field and the second toner image is transferred the receiver using a second electrostatic field.
