Title: Toner for developing electrostatic charge image and image forming method using same
Inventor: KATO KOICHI
IPC: G03G9/087
Filed: 1990-02-21
Abstract: PURPOSE:To inhibit the reduction of a toner to fine powder, to prevent filming on a photosensitive body and a developing sleeve and to stably maintain the triboelectric chargeability of the toner by rendering specified mechanical characteristic values. CONSTITUTION:When toner powder is melted and solidified to form a plate, such mechanical characteristic values as 20-80kg.cm/cm Izod impact value, 400-950kg/cm<2> tensile yield strength and 400-2,000kg/cm<2> bending strength are rendered. The resulting toner having specified physical surface properties is produced by mixing a binding resin such as polystyrene or a styrene-butyl methacrylate copolymer with low mol. wt. polypropylene, adding a colorant and a charge controlling agent, melting and kneading them with prescribed energy applied to the resins and carrying out pulverization and classification. The reduction of the toner particles to fine powder is inhibited, filming between a developing sleeve and a photosensitive body is also inhibited and a high-quality copied image is formed.

Abstract: PROBLEM TO BE SOLVED: To provide a D/A converter capable of improving the S/N by increasing a quantization bit number of a delta sigma modulation circuit without a remarkable increase in the circuit scale. SOLUTION: In this D/A converter 1, a 2nd digital signal 28 outputted from a delta sigma modulation circuit 2 is decoded by a decode circuit 3, and a D/A converter circuit 4 outputs an analog signal in response to a 2nd digital signal based on the decode result. The delta sigma modulation circuit applies nonlinear quantization to an input signal, where a large quantization error is given to the input signal corresponding to a large analog absolute signal. The deterioration of the S/N is minimized through the nonlinear quantization in comparison with linear quantization in the same bit number and the number of switches for selecting division voltage.

Abstract: PROBLEM TO BE SOLVED: To lessen the labor required for exposure work of patterns in a pattern transfer method for a large-sized substrate. SOLUTION: An exposure pattern consists) of regular patterns 1 and an outer frame pattern 2 of a rectangular shape. The exposure pattern is divided to end patterns 3, 4 and an inner pattern 5 on the inner side thereof.

The divided patterns 51 are formed at the center of the mask 6 and the both end patterns 3, 4 are formed at both ends thereof by reversing the arrangement in the long side direction from the arrangement on the exposure pattern. The divided patterns 51 of the mask 6 are transferred twice in juxtaposition to the prescribed position on the substrate 8 and thereafter, the end patterns 3, 4 are transferred.  At the time of the exposure of the end patterns 3, 4, the divided patterns 51 of the mask 6 do not overlap on the substrate 8 and, therefore, there is no need for shielding the mask 6.

Filed: 1987-02-27
Abstract: PURPOSE:To reduce the size and cost of a device by generating modulated light, deflecting the same nearly perpendicularly, deforming the sectional shape of the light and scanning the deflected and deformed light. CONSTITUTION:A semiconductor laser 56 generates the laser beam L modulated according to image information and the laser beam L collimated by a collimator lens 58 is reduced only in one direction of the sectional shape and is deflected nearly perpendicularly by two pieces of triangular prisms 66 so as to be reduced to a suitable spot size on a photosensitive drum 14. A rotary polyhedral mirror 60 deflects and scans the laser beam L deflected by the triangular prisms 66, 66 by as much as the width corresponding to the recording region on the drum 14. Since the shaping and deflecting of the light from the light generating means are thereby simultaneously executed by an optical means, the size and cost of the device are reduced.

Abstract: PURPOSE:To quickly obtain a stable fixing temperature via the application of only power supply voltage by heating and press fixing, via a medium, an unfixed image on a transfer and fixing belt onto a heating body having a self- temperature control element. CONSTITUTION:An unfixed image carried on a transfer and fixing belt 12 comes in contact with a media 15 synchronously fed with the unfixed image at an NIP section. The unfixed image is heated and melted with an exothermic body 9 at the NIP section, and concurrently pressed with an elastic rubber roller 10, thereby being fixed on the media 15. In this case, the surface of the transfer and fixing belt 12 is treated with fluorine or the like, and has high mold releasability. Thus, the unfixed image is efficiently fixed. The exothermic body 9 is flat type and formed with a PTC thermister of self-temperature control type. Heat thereby generated quickly rises to the predetermined temperature only with a 100 VAC power supply and without any need of a temperature control circuit, and can be stably insulated.
