    • A compositional range for a mother glass composition for graded index lenses which has a desired refractive index and is less apt to be devitrified and to develop cracks upon ion exchange was obtained by incorporating at least a given amount of one or more ingredients which are selected from oxides of metal elements ranging from yttrium, atomic number 39, to tantalum, atomic number 73, and which are less apt to cause glass coloration into a glass based on SiO2—TiO2—Li2O—Na2O and containing no lead oxide. In particular, a compositional range in which a large angular aperture is obtained and devitrification is less apt to occur was obtained by incorporating Ta2O5 and ZrO2 in a specific proportion and in specific amounts.

    • Impurities contained in a developer are captured and prevented from mixing into the developer again, thereby to avoid lowering of image quality due to the impurities. Such impurities include aggregates of the developer formed in a developing apparatus, insufficiently charged toner particles, defectively charged toner particles having an opposite polarity to a predetermined polarity, and defective carrier particles lacking in strength for being held by a developing magnet roller. A recess is provided between peaks of magnetism located in a lower portion of a developing magnet roller. The recess has an air pressure substantially equal to an air pressure (atmospheric pressure) in the developing apparatus, so that air in the developing apparatus and the recess does not flow only in one direction. Impurities contained in the developer circulating around the developing roller cannot be magnetically held in the lower half of the developing roller because of centrifugal force and gravity. Consequently, the impurities are separated and collected in the recess.
    • 包含在显影剂中的杂质被捕获并防止再次混入显影剂中,从而避免由于杂质而导致的图像质量降低。 这样的杂质包括在显影装置中形成的显影剂的聚集体,充足的调色剂颗粒,具有与预定极性相反的极性的缺陷充电的调色剂颗粒,以及由显影磁性辊保持的强度不足的载体颗粒不良。 在位于显影磁辊的下部的磁性峰之间设置凹部。 凹部的空气压力基本上等于显影装置中的空气压力(大气压),使得显影装置中的空气和凹部不仅在一个方向上流动。 由于离心力和重力,包含在显影辊周围显影剂中的杂质不能磁性地保持在显影辊的下半部。 因此,杂质被分离并收集在凹部中。

    • By using a thermal development type photosensitive recording medium wherein a latent image is formed in a photocuring composition by exposure, and in which the components related to thermal color development or thermal color bleaching are diffused to form a color picture image within the photosensitive material correponding to the latent image, a picture signal representing a picture is received and an image of the picture is displayed on a liquid crystal panel as a black and white picture image corresponding to the picture signal. The displayed picture image on the liquid crystal panel is exposed on the photosensitive recording medium. Monomer is polymerized in the exposed areas by a photopolymerization initiator. The components related to color development or color bleaching of the unexposed areas are diffused by means of heating the photosensitive recording medium, and a visible picture is formed.
