A rotary developing unit includes: a first developing device; a second developing device; a toner supply container that is inserted between the first developing device and the second developing device to be attached to the first developing device; a first guide formed on the toner supply container; a second guide formed on the second developing device, that is configured to slide along the first guide when the toner supply container is inserted, and to be detached from the first guide before the toner supply container is attached to the first developing device; a first position fixing unit provided at the first developing device; and a second position fixing unit provided at the toner supply container, that is configured to fix a position of the toner supply container, before the second guide of the second developing device is detached from the first guide.
摘要:
An image forming apparatus includes plural toner image forming devices. Each of which has a rotating photoconductor, a charging device that uniformly charges a surface of the photoconductor, a latent image forming device that forms an electrostatic latent image on the surface of the charged photoconductor, a developing device that develops the electrostatic latent image on the surface of the photoconductor to a toner image, and a developing container that contains toner used by the developing device. A diameter of the photoconductor of at least one toner image forming device is formed larger than a diameter of the photoconductor of the other toner image forming devices. Each developing container of all the toner image forming devices is formed in equal-sized, and a center of rotation of a developing roll of each developing device is arranged in a position upper than a center of rotation of each photoconductor.
摘要:
A hydrated granular carrier is prepared for microbe immobilization in a biological treatment apparatus such as for treating waste water and exhaust gas. The carrier contains hydrated granular gel particles coated with a finely ground organic powder. The gel particles are made of a polymer insoluble in cold water but soluble in hot water. In making the hydrated gel particles, heated water is added to the polymer while stirring at high speed. Then, the finely ground organic powder is added together with heated water while stirring at high speed to coat the finely ground organic powder on the gel particles. Preferably, the polymer is polyvinyl alcohol having a degree of polymerization of 1000 to 2500 and a degree of saponification of 98% or more. Heated water added to the polyvinyl alcohol is added by spraying at 10 to 15 liters per minute at a temperature of 40.degree. to 100.degree. C. in an amount of 50 to 150 parts by weight based on 100 parts by weight of the polyvinyl alcohol. The organic powder is activated charcoal having a particle size of 200 mesh or less in an amount of 3 parts by weight or more, and the water added with the charcoal is at 40 to 100.degree. C. in an amount of 5 to 20 parts by weight. The high speed stirring is at 500 to 1000 rpm.

A developer transporting device includes a transporting device body including a transporting portion having an inlet, a developer container including a container portion having an outlet connected to the inlet and a cover member that is movable between positions for opening and closing the outlet, a first contact portion supported by the cover member, a guide portion including a passage portion and an inclined portion that is connected to the passage portion and that comes into contact with the first contact portion to move the cover member, and a second contact portion that is provided on the passage portion and extends toward the position for closing the outlet. The second contact portion comes into contact with the first contact portion and moves the cover member toward the position for closing the outlet when the first contact portion passes the second contact portion.
摘要:
A drive transmission structure includes a driven shaft, a drive shaft, and a bearing member. The driven shaft has a drive receiving gear attached thereto and a first shaft portion near the drive receiving gear, to which a rotational force is transmitted. The drive shaft has a drive transmitting gear attached thereto and a second shaft portion near the drive transmitting gear. The drive transmitting gear is engaged with the drive receiving gear so as to transmit the rotational force. The bearing member has a first bearing and a second bearing, which respectively support the first shaft portion and the second shaft portion. In the drive transmission structure, the axis of the drive shaft does not intersect and is non-parallel to the axis of the driven shaft, and the first and second bearings are integrally formed with the bearing member.
