    摘要： A developing device includes a developer roller, a stir-and-transport member, and a layer thickness regulating member. The developer roller may carry developer to a photosensitive body. The stir-and-transport member may supply the developer to the developer roller. The layer thickness regulating member is located adjacent the developer roller to remove excess developer. The layer thickness regulating member includes a guide element to direct the excess developer to the stir-and-transport member.

    摘要： A device to develop an electrostatic latent image in an imaging apparatus includes first and second passages coupled to each other through first and second openings to form a circulation passage. A first stir-and-transport member is located in the first passage and includes a first helical blade to stir and transport a developer from the first opening to the second opening along the first passage in a first direction and to supply the developer to a developing roller. A second stir-and-transport member is located in the second passage and includes a second helical blade to stir and transport the developer from the second opening to the first opening along the second passage in a second direction. A developer discharge pipe is coupled to the developer container to communicate with a downstream side of the first passage. The first stir-and-transport member includes a first reverse helical blade located downstream of the first helical blade and disposed downstream of the second opening. The pitch of the first reverse helical blade is between approximately 0.5 times and 1.5 times the pitch of the first helical blade.

    摘要： Electrically conductive electrostatic ink compositions are disclosed. In an 5 example, an electrically conductive electrostatic ink composition can comprise: a liquid carrier; and particles dispersed in the liquid carrier. The particles dispersed in the liquid carrier can comprise: thermoplastic resin, and electrically conductive metal particles. The electrically conductive metal particles can comprise: a core comprising a first metal, and a shell comprising a second 10 metal. The shell can enclose the core at least partially. The first metal and the second metal may not be the same.

    摘要： The present disclosure relates to chemically processed toner that makes use of aqueous dispersions of release agent and/or pigment and solutions of a polymeric resin binder. The polymer solution may be prepared in an organic solvent wherein the organic solvent has some level of solubility in water. The polymer solution may then be combined with an aqueous dispersion of pigment and/or release agent which dispersions may include an aqueous polyelectrolyte and/or an aqueous dispersion of colloidal particles. This may be followed by agglomerating and forming particles of toner of a desired number and/or volume average particle size and/or degree of circularity.
