摘要:
A carrier and a dummy toner are stored in a developing unit of a process cartridge in a brand new status. A plurality of process cartridges corresponding to a plurality of color toners is used in common. The color toners are respectively supplied to the developing unit from toner supply units after the process cartridges in the brand new status are installed in installation sections in a main unit of an image forming apparatus.

摘要:
A process cartridge is provided with a frame body made up of at least first and second frame bodies that are movable relative to each other to form a space, a frame body positioning member positioning the first and second frame bodies, a latent image bearing member supported by the frame body and replaceable via the space formed by the first and second frame bodies, a developing unit supplying a developing agent to the latent image bearing member, and a developing position determining member. The developing position determining member is disposed at a non-overlapping position relative to the frame body positioning member, and positions the developing unit with respect to the frame body.

摘要:
The image forming apparatus comprises a photoconductor, a latent electrostatic image forming unit for forming a latent electrostatic image on the photoconductor, a developing unit for developing the latent electrostatic image using a developer comprising a toner to form a visible image, a transfer unit for transferring the visible image to a recording medium, a cleaning unit for removing the developer remained on the photoconductor surface and a developer amount detection unit for detecting developer amount adhering to the photoconductor surface by a reflecting photosensor, wherein the developer stirring time per copy when one copy is made from an original, is 2 to 6 times the developer stirring time per copy when two or more copies are made from the original, wherein the toner comprises at least a binder resin and a wax, and the dynamic frictional coefficient of the toner is 0.15 to 0.45.
摘要:
A developing device includes a casing to contain developer, a developer bearer disposed in the casing and opposite a latent image bearer in a developing range, at least one developer contact face to which the developer adheres in image formation, and a vibrator to give vibration to the developer contact face in a non-image formation period. The developer bearer is to rotate to supply the developer to the latent image bearer in the developing range.
摘要:
A multi-functional admixture for simultaneously providing specified characteristics to hydraulic cement compositions such as concrete contains one or more of specified reaction mixtures obtained by specified two processes as well as partially or completely neutralized substances obtained from such a reaction mixture through a specified third process. The specified two processes include initiating a radical copolymerization process of a radical polymerizable monomer mixture containing maleic anhydride and a monomer of a specified kind in a non-aqueous system in the presence of a non-aqueous radical initiator and stopping the radical copolymerization reaction in its midst while the inversion rate of polymerization is at a specified level by adding water to the reaction system to thereby obtain a reaction mixture. The specified third process is for partially or completely neutralizing the reaction mixture.
摘要:
A high-strength hydraulic cement composition contains cement, fine aggregates, coarse aggregates, water and a specified admixture and has a unit amount of water in the range of 120-185 kg/m3. Water and the cement are contained at a ratio of 20-40% and the admixture is contained in the amount of 0.1-3.0 weight parts per 100 weight parts of the cement. The admixture is one or more selected from reaction mixtures obtained by specified two processes and partially or completely neutralized substances obtained from such a reaction mixture through these two processes and also a specified third process. The specified two processes include initiating a radical copolymerization process of a radical polymerizable monomer mixture containing maleic anhydride and a monomer of a specified kind in a non-aqueous system in the presence of a non-aqueous radical initiator and stopping the radical copolymerization reaction in its midst while the inversion rate of polymerization is at a specified level by adding water to the reaction system to thereby obtain a reaction mixture. The specified third process is for partially or completely neutralizing the reaction mixture.
