Abstract

A resilient roller having particular use as one of two co-operatingrollers of an xerographic development system, one of which is an applicator roller for liquid developer and the other of which carries an electrostatic latent image. The roller comprises a rigid core 1, e.g., of metal, wood, plastic or hard rubber, a flexible, generally cylindrical shell 2 and an elastic substance 3 (such as neoprene, nitrile, butyl, polyurethane or silicone rubber) positioned between the core and the shell.

FIG. 2

A resilient roller having particular use as one of two co-~operatingrollers of an xerographic development system, one of which is an applicator roller for liquid developer and the other of which carries an electrostatic latent image. The roller comprises a rigid core 1, e.g., of metal, wood, plastic or hard rubber, a flexible, generally cylindrical shell 2 and an elastic substance 3 (such as neoprene, nitrile, butyl, polyurethane or silicone rubber) positioned between the core and the shell.

Shaped end plates 4 engage the elastic substance 3 to maintain it in compression so that it grips the core 1 and the shell 2. Profiling of the end plates 4 provides

spaces .5 into which the elastic substance may flow during assembly and temperature increases. In order to improve the uniformity of the expansion of the elastic substance, the core has outwardly facing, longitudinal grooves 6 (Figure 2),

which provide expansion spaces for the elastic substance. These may be used in addition to or instead of the spaces 5.
