摘要:
A display system is built up of at least one display cell comprising an assembly which has at least a first electrode and a second electrode and in which there are mutually non-miscible first and second liquids filled, wherein either one of the first and second electrodes is electrically insulated from the first and second liquids, the first liquid has electrical conductivity or polarity, and voltage is applied to one or both of the first and second electrodes, whereby the first liquid and the second liquid can vary in position to produce a display. Even after an applied voltage is shut off at a position to which the first and second liquids have migrated, the positions of the first and second liquids that have migrated are retained to keep memory capability going on.

The invention provides an electrophotographic photoreceptor having a cylindrical support, and a charge-generating layer and a charge-transporting layer on or above the cylindrical support, wherein the thickness of the charge-generating layer is increased from the central portion in the axial direction of the cylindrical support towards both end portions thereof, and the difference in thickness between the two end portions is 2.5% or less of an average thickness of the charge-generating layer. Also disclosed are a method of producing the electrophotographic photoreceptor, a process cartridge including the electrophotographic photoreceptor, and an image-forming apparatus.
摘要:
An apparatus for forming an image using an electrophoretic particle suspension containing media including: a transitioner for sufficiently lowering a viscosity of the suspension to facilitate mobility of at least some of the electrophoretic particles; and, imaging electrodes for selectively providing an imaging electric field associated with the image to be formed and positioned with respect to the transitioner such that the imaging electric field impinges upon the lowered viscosity suspension; wherein, the imaging electric field is sufficient to cause select ones of the electrophoretic particles in the lowered viscosity suspension to migrate depending upon the image to be formed. The media includes a plurality of substrates defining an interior hollow including an electrophoretic particle containing, phase-transitional suspension suitable for enabling migration of the electrophoretic particles responsively to an applied electric field in a first state and substantially impeding migration of the particles in a second state.
