Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To obtain an excellent water absorbing agent having a well balanced absorption factor, absorption speed and liquid permeability by fixing a water- absorbing fine particle having an absorption factor lower than that of a water absorbing resin particle on a surface of the water absorbing resin particle. SOLUTION: The absorption factor of a water absorbing fine particle to be fixed on a surface of a water absorbing resin particle is essentially lower than that of the water absorbing resin particle. In this case, preferably, the absorption factor of the water absorbing fine particle is to be not higher than 80% of that of the water absorbing resin particle. The absorption factor is evaluated by using deionization. In this case, preferably, the absorption factor of the water absorbing resin particle to a deionized water is about 200 g/g or higher and the absorption factor of the water absorbing fine particle to the deionized water is 1.5-100 g/g. Further, in a preferred state of fixture of the water absorbing fine particle, at least a part of the water absorbing fine particles is embedded in the surfaces of the water absorbing resin particles in a partially protruding way.

Title: Color image forming device
Inventor: TAKAHASHI MASAKI
IPC: G03G15/16
Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To eliminate the irregularity of image density caused by the pulsation of the speed of a photoreceptor and a speed error and displacement in superimposition caused in a color image by setting tangential drive force of the photoreceptor greater than tangential drive force of an intermediate transfer body. SOLUTION: A drive motor for a photoreceptor drum and a drive motor for an intermediate transfer drum are provided, and the output torques of the drive motors for both drums are set so that the tangential force the photoreceptor drum exerts on the intermediate transfer drum is greater than the tangential force the intermediate transfer drum exerts on the photoreceptor drum. Thus, in the contact part of the photoreceptor drum and intermediate transfer drum, the driving force for the photoreceptor drum overcomes the other, and hence the surface velocity of the photoreceptor drum and the surface velocity of the intermediate transfer drum are determined by the photoreceptor drum.  On the other hand, both the drums are in contact with each other with high pressure, and hence even in the case a high rotation load occurs in the photoreceptor drum, the driving force from a drive source of the intermediate transfer drum drives the photoreceptor drum so as not to overcome the driving force for the photoreceptor drum and this enables the photoreceptor drum to maintain stable revolving speed all the time.
