摘要： A developer agitator of an image forming device capable of improving the electrification rate of a developer is disclosed. The developer agitator includes a rotatable shaft and an agitating wing disposed on the circumferential surface of the shaft. The agitating wing has an uneven part formed to increase the contact area with a developer. The developer agitator can obtain an electrification rate of the developer required for high speed printing, thereby allowing the image forming device to be operated at a high speed.

摘要： An image printing apparatus includes a photoreceptor belt on which a latent electrostatic image is formed, and a plurality of development devices for developing the latent electrostatic image formed on the photoreceptor belt. Each of the development devices has a development roller for coating a developer liquid on the photoreceptor belt, and a squeegee roller for removing excess developer liquid from the photoreceptor belt. A roller driving means drives the squeegee rollers, and an elevating means elevates the development devices. The plurality of development devices are supported by a pair of frames that are spaced apart a predetermined distance from each other. The roller driving means commonly drives the squeegee rollers of the development devices. The frame elevating means displaces the pair of frames, such that the squeegee rollers are simultaneously in contact with or out of contact with the photoreceptor belt.

摘要： A photosensitive belt installation device of an electrophotographic image forming apparatus that includes a soft cartridge which rolls up for storage, and an installation guide member which selectively attaches to the image forming apparatus. When unrolled, the cartridge, allows the simple installation of a photosensitive belt into the imaging forming apparatus. The soft cartridge is a flexible cartridge having a shape of the endless track of a belt unit of the imaging forming apparatus, and is open on both sides. The unrolled soft cartridge supports the photosensitive belt during installation, as one open side of the soft cartridge is fitted over a sloping surface of the installation guide member attached to the front frame of the belt unit. The soft cartridge is completely pushed around the belt unit along a sloping surface of the installation guide member. The photosensitive belt remains around the belt unit as the soft cartridge is pulled out. The installation guide member is then be removed from the front of the belt unit.

摘要： An ink feeding valve of a wet type electrophotographic printer, capable of basically preventing operational error and incapability of valve due to ink attachment, includes: a valve body having a pipeline for interconnecting the concentrated ink tank with the developing solution tank; a rod assembly disposed in the pipeline of the valve body so as to be vertically moved for selectively opening/closing the pipeline; an elevating section for vertically moving the rod assembly; and a corrugated tube disposed in the pipeline of the valve body for partitioning the pipeline into an inner ink passage and an outside elevating section operating chamber, and for preventing ink flow into the elevating section operating chamber. Since the ink passage and the elevating section operating chamber are isolated from each other by the presence of a corrugated tube, the plunger and spring located in the elevating section operating chamber are efficiently operated without having problems caused due to ink attachment. Accordingly, ink can be consistently fed and operational problems avoided.
