Abstract
Imaging apparatus including squeegee apparatus for squeegeeing excess material from a surface, from which surface at least a portion of the material remaining after squeegeeing is to be transferred to another surface, comprising: a first surface, having a central portion and two end portions having recessed surfaces and having a liquid material thereon at least in said central portion, said surface moving in a given direction at a squeegee region; and a second, squeegee, surface, urged against at least the central portion of the first surface at the squeegee region and formed with contiguous end portions which mate with the recessed end surfaces of the first surface.
Claims58
Imaging apparatus including squeegee apparatus for squeegeeing excess liquid from a surface, comprising:
- a first surface, having a central portion and two end portions having recessed surfaces and having material thereon at least in said central portion, said surface moving in a given direction at a squeegee region, said material comprising at least a liquid;
- and
- a second, squeegee, surface, urged against at least the central portion of the first surface at the squeegee region, such that the squeegee surface removes at least a portion of the liquid on the first surface, said squeegee surface being formed with contiguous end portions which mate with the recessed end surfaces of the first surface,
- wherein at least a portion of the material remaining on the first surface after removal of a portion of the liquid by the squeegee surface is transferred from the first surface to another surface.
Imaging apparatus comprising:
- an imaging surface, having a latent electrostatic image formed thereon, which moves in a first direction at a development region;
- a first, developer, surface, having a central portion and two end portions having recessed surfaces, said central portion being urged against the imaging surface and moving therewith in the first direction at a development region and moving in a given direction at a squeegee region prior to the developer surface entering the development region;
- and
- a second, squeegee, surface, urged against at least the central portion of the developer surface at the squeegee region.
Imaging apparatus including squeegee apparatus for squeegeeing excess liquid from liquid toner, comprising toner particles and carrier liquid, from a surface, from which surface at least a portion of the liquid toner remaining after squeegeeing is to be transferred to a surface other than the squeegee, comprising:
- a first surface having a central portion and two end portions having recessed surfaces and having a liquid toner material, comprising toner particles and a liquid carrier thereon, at least in said central portion, said surface moving in a given direction at a squeegee region;
- and
- a second, squeegee, surface, urged against at least the central portion of the first surface at the squeegee region and operative to remove at least a portion of the liquid carrier from the liquid toner material, prior to transfer of at least a portion of the material remaining after said removal, to a third surface.
