摘要:
The undesirable image defect of dragout of liquid ink development (LID) toned images generated from the development zone, formed by an imaging member and a metering/development member, can be prevented. Background development of the toned images is suppressed in an image enhancement zone. With the aid of an enhanced electrostatic field, created by an electrode biased at a voltage other than normal development bias in the metering zone, the toned layer can resist higher viscous forces. Image dragout, due to the viscous shear from liquid ink, can therefore be eliminated.
