Abstract

The Figures illustrate a liquid developer dispenser roll for dispensing a liquid developer to a patterned developer applicator roll which may be useful in developing an electrostatic latent image on an electrostatographic imaging surface. Figure 1 is a cross sectional view of the liquid developer dispensing roll which comprises an outer foam roll 10 with a solid interior 12 having three holes 14, 16 and 18 therein connected to tubes or channels 14a, 16a and 18a. The tubes or channels extend across most of the diameter of the roll and are open at ends 20,22 and 24.

LIQUID DEVELOPER DISPENSER ROLL (Cont'd)

The Figures illustrate a liquid developer dispenser roll for dispensing a liquid developer to a patterned developer applicator roll which may be useful in developing an electrostatic latent image on an electrostatographic imaging surface. Figure 1 is a cross sectional view of the liquid developer dispensing roll which comprises an outer foam roll 10 with a solid interior 12 having three holes 14, 16 and 18 therein connected to tubes or channels 14a, 16a and 18a. The tubes or channels extend across most of the diameter of the roll and are open at ends 20,22 and 24.

During operation with liquid developer filling about 112 the roll capacity, the roll is rotated and when it rotates liquid developer at the bottom of the roll is picked up by the holes in the tubes, transported the length of the tube through the dispensing holes 14, 16 and 18 and into the outer foam roll. When at rest, only one of the holes is at the bottom and accordingly only a small amount of developer will be dispensed to the foam from the hole, the developer in the interior being contained by the solid interior 12. Figure 2 is a side view of a portion of the foam applicator roll showing one of holes 14, 16...
