    • The present invention relates to an image forming apparatus 1 including a photosensitive member 2 on which an electrostatic latent image is formed according to an image signal, a development mechanism 5 for forming a toner image by developing the electrostatic latent images, and a transfer body 60 for transferring the toner image. The development mechanism 5 includes a plurality of developing units 51-54 holding different kinds of toners. A second work of adhesion between the photosensitive member 2 and a second toner to be transferred to the transfer body second is larger than a first and a third work of adhesions between the photosensitive member 2 and a first and a third toners to be transferred to the transfer body first and third.
    • 本发明涉及一种图像形成装置1,其包括根据图像信号形成静电潜像的感光构件2,用于通过显影静电潜像形成调色剂图像的显影机构5和转印体60 用于转印调色剂图像。 显影机构5包括保持不同种类的调色剂的多个显影单元51-54。 感光构件2和第二调色剂之间的第二粘附作用将被传送到转印体第二调色剂中,大于在感光构件2和第一和第三调色剂之间的第一和第三粘附作用,以将其转印到 转运身体第一和第三。

    • A process of producing expandable styrene resin particles, wherein in suspension polymerization of styrene monomers, the concentration of oxygen in a reaction vessel is kept low at least in a late stage of the polymerization, and the resulting styrene resin particles are impregnated with an expanding agent before or after completion of the polymerization. Preferably, at a polymerization rate of 60% or higher, the concentration of oxygen in the reaction vessel is kept at 7 vol % or lower. When additional styrene monomers are added during the polymerization, they are added and adsorbed to styrene resin particles in the course of polymerization while the concentration of oxygen is kept low. By this method, the particles whose internal portion has a low molecular weight and surface portion has a high molecular weight are obtained. A foamed article produced from the particles has high strength and a good appearance.
    • 一种生产可发性苯乙烯树脂颗粒的方法,其中在苯乙烯单体的悬浮聚合中,至少在聚合的后期将反应容器中的氧浓度保持在较低水平,所得到的苯乙烯树脂颗粒用发泡剂 在聚合完成之前或之后。 优选以60%以上的聚合速度将反应容器内的氧浓度保持在7体积%以下。 当在聚合期间加入另外的苯乙烯单体时,它们在聚合过程中被加入并吸附到苯乙烯树脂颗粒上,同时氧气的浓度保持较低。 通过这种方法,可以获得其内部具有低分子量和表面部分的颗粒具有高分子量的颗粒。 由颗粒制成的发泡制品具有高强度和良好的外观。
