    摘要： The present invention relates to a color copying apparatus which prevents toner scattering from a tip portion of a cleaner to an image area of an image carrying drum. An exposing device forms a stripe latent image in a stripe area at an upstream of the image area of an image carrying drum in a rotating direction of the image carrying drum, and a developing device stops development within the stripe area. The result is a generation of a sharp potential gap in the stripe area. The cleaner starts cleaning by touching to the stripe area, and accumulated toner on the tip of the cleaner is attracted by the sharp potential gap and is held within the stripe area. This prevents the toner from being scattered to the image area of the image carrying drum.

    摘要： There is described a fixing device equipped in an image forming apparatus, which employs an electro-photographic method for forming an image on a transfer material, and having a lifetime longer than conventional one. The fixing device includes a first roller having a first elastic layer formed in a cylindrical shape on an outer surface of the first roller; and a second roller having a second elastic layer formed in a cylindrical shape on an outer surface of the second roller. A hardness of the second elastic layer is higher than that of the first elastic layer, and a nip section is formed between the first elastic layer and the second elastic layer. A longitudinal length of the first elastic layer in an axial direction of the first roller is greater than that of the second elastic layer in an axial direction of the second roller.

    摘要： In a gas-discharge display device, a plurality of parallel cathodes connected to cathode terminals (K.PHI..sub.1 to K.PHI..sub.4) by multiphase connection are disposed in equally spaced apart relation on one surface of a substrate, while a plurality of parallel and equally spaced-apart anodes are disposed on the rear surface of a face plate in a relation crossing with the cathodes, and the fact plate is superposed on the substrate through barrier ribs defining a discharge space. In the display device, time-serial multiphase pulse voltage trains are applied to the individual cathodes respectively, while a train of pulses of large width corresponding to display information is applied to each of the anodes in a relation superposed on a train of pulses of small width used for initiation of an auxiliary discharge.
