Abstract
A roller device and method for maintaining a uniform surface contact along a line of axial trangency with respect to one or more rigid cooperating surfaces having irregularities, the roller device comprising a rigid solid- or cylindrical-type core loosely circumscribed axially with a flexible sleeve, the space between the core and the sleeve being substantially equidistant and filled with a curable plastic foam material to obtain a uniform contact and nip width when in rotational contact with a cooperating surface.
Claims8
A method for effecting and maintaining a uniform substantial interface contact for liquid xerographic development between a xerographic liquid toner applicator roll and a cooperating electrostatic latent image-bearing surface, one of which is rigid and contains surface irregularities, and the other a non-rigid member comprising:
- a. a rigid core and end-supporting means;
- and
- b. a flexible sleeve mounted over the core component of the core and end-supporting means, said sleeve maintaining functional integrity as a photoreceptor or liquid developer applicator having a pattern of lands and valleys, and in contact with the interfacing member;
- comprising effecting liquid development of the latent electrostatic image by developmental contact, with a latent electrostatic image, utilizing as part of the non-rigid member a flexible sleeve with a substantially greater circumference than the core component and spaced substantially uniformly apart from the core component by attachment to end supporting means and by particularly cured low temperature curing monomer-containing foam material intermediate the core and the sleeve to maintain a spaced relationship between the core component and the flexible sleeve.
