    摘要: A toner for developing an electrostatic image is provided as a pulverized mixture including a binder resin and a colorant. The binder resin is characterized by a molecular weight distribution on a GPC chromatogram of its tetrahydrofuran (THF)-soluble resin content including at least 15% and below 35% of a resin component in a molecular weight region of at most 5000 and at least 3 wt. % of a resin component in a molecular weight region of at least 5.times.10.sup.6 and showing a main peak in a molecular weight region of 5000 to 10.sup.5. The binder resin also has an acid value of 2-100 mg KOH/g. The THF-soluble resin component in the molecular weight region of at least 5.times.10.sup.6 is enriched during a melt-kneading step during the toner production.

    摘要: An optical deflection element receives incident beam and deflects the incident beam with an arbitrary deflection angle. The optical deflection element includes a plurality of unit members which are successively stacked and each including an electrooptic layer, an electrode layer formed on a surface of each electrooptic layer, and an insulator layer formed on the surface of each electrooptic layer adjacent to the electrode layer, where a boundary between the electrode layer and the insulator layer is inclined to an optical axis of the incident beam.

    摘要: A process for classifying toner particles supplied through a supply nozzle into at least three fractions in a classifying chamber divided into at least three sections and placed under a reduced pressure under the action of the inertia force of the toner particles supplied together with a gas stream and the centrifugal force of the curved gas stream due to Coanda effect. A first gas introduction pipe and a second gas introduction pipe are disposed above the classifying chamber so as to provide a first inlet and a second inlet opening with the first inlet being disposed closer to the supply nozzle than the second inlet. The absolute values of the static pressures P.sub.1 and P.sub.2 in the first and second gas introduction pipes are controlled so as to satisfy the relations of: .vertline.P.sub.1 .vertline..gtoreq.150 mm.aq., .vertline.P.sub.2 .vertline..gtoreq.40 mm.aq. and .vertline.P.sub.1 .vertline.-.vertline.P.sub.2 .vertline..gtoreq.100 mm.aq.
