Abstract: According to the present invention, the method for producing toner for developing an image of electrostatic charge comprises the steps of producing a dispersion liquid of flocculated particles by forming the flocculated particles in a dispersion liquid comprising at least dispersed resin particles, forming combined particles by dispersing a liquid dispersion comprising dispersed fine resin particles into the dispersion liquid of flocculated particles so that the fine resin particles adhere to the flocculated particles and forming toner particles by fusing the combined particles by heating, wherein the molecular weight distribution curve of the resin in the toner particles by a gel permeation chromatography has at least two peaks or shoulders. According to the present invention, it is possible to produce toner for developing an image of electrostatic charge which is particularly superior in chargeability and the stability of the chargeability.

Abstract: A depleted-gate photosensor, or photogate, structure includes a polysilicon layer disposed over a silicon substrate. The polysilicon layer occupies only a portion of each exposure area of the substrate, and is preferably in the form of a ring around the exposure area. By having a portion of the exposure area not covered by the polysilicon, the blue-light-attenuation effects of a polysilicon layer are reduced.

Abstract: A thin film organic light emitting diode with edge emitter waveguide comprises, in sequence, a substrate, a waveguide, an anode, a hole transport layer, an electroluminescent layer, and a cathode. Voltage applied between the anode and cathode causes the electroluminescent layer to emit light through the hole transport layer and the anode into the waveguide where the light is internally reflected within the waveguide and propagates through the length of the waveguide to be emitted through the edge of the waveguide. The non-emission edge of the waveguide may be sloped with a conductor layer to the anode and a conductor layer to the cathode forming a reflective surface to the non-emission edge.
