An anisotropic conductive film composition, an anisotropic conductive film prepared using the same, and a connection structure using the same, the anisotropic conductive film including a binder resin; a curable alicyclic epoxy compound; a curable oxetane compound; a quaternary ammonium catalyst; and conductive particles, wherein the anisotropic conductive film has a heat quantity variation rate of about 15% or less, as measured by differential scanning calorimetry (DSC) and calculated by Equation 1:Heat quantity variation rate (%)=[()/]&#xd7;100&#x2003;&#x2003;Equation 1

Composition for anisotropic conductive film, anisotropic conductive film, and connection structure using the same

Provided is a developing device configured to develop an electrostatic latent image formed on an image bearing member by feeding a toner to the electrostatic latent image. The developing device includes a developing frame configured to form an inner space in which the toner and a carrier are to be mixed, a developing roller including an outer periphery to which the developer attaches where the developing roller feeds the toner included in the developer to the image bearing member. The developing device includes an agitator installed in the inner space and configured to mix and deliver the toner and the carrier in a direction parallel to an axial direction of the developing roller, and a plurality of concave portions arranged on a bottom surface of the developing frame.

Developing device to charge and mix toner and electrophotographic image forming apparatus including the same

An inkjet image forming apparatus includes a main body frame, a medium supplying unit which is coupled to the main body frame and supplying a print medium, an image forming cartridge which is coupled to the main body frame, forms an image on the supplied print medium, and including a nozzle to eject ink, and a wiping assembly which wipes the nozzle. The wiping assembly includes a wiping sheet storage unit in which the wiping sheet is stored as being wound, a transfer shuttle which moves along arrangement of the nozzle by a driving force of a driving source, a pressing member which is provided in the transfer shuttle and presses a region of the wiping sheet against the nozzle to perform wiping using the wiping sheet, and a wiping sheet support unit which is provided in the transfer shuttle and restricts move of the wiping sheet while the nozzle is wiped.

Wiping assembly and image forming apparatus having the same

An image-forming apparatus includes a print head unit including a plurality of head chips disposed in a widthwise direction of a supplied printing medium to eject ink to form an image, a wiping unit including a plurality of wiper members disposed in the widthwise direction of the printing medium, and a support member supporting the plurality of wiper members and located below the print head unit to move upwardly and downwardly. The image-forming apparatus also includes an ink discharging unit which accommodates and discharges ink spitted from the print head unit, an elevating driving unit which moves the wiping unit upwardly and downwardly between at least two positions of a first forward position which is a wiping standby position, a second forward position which is a scrapping position, and a retracted position, and a widthwise direction driving unit which reciprocates the wiping unit positioned in the first or second forward positions by the elevating driving unit.

Print head maintenance apparatus and image forming apparatus having the same

A scrapping unit and an image forming apparatus having the same, and cleaning methods thereof to improve a maintenance performance. The scrapping unit cleans a polluted member disposed in an image forming apparatus and stained by a polluting material. The scrapping unit may include an endless belt to circulate between an exposed position where a surface of the endless belt is exposed toward the polluted member, and a non-exposed position where the surface of the endless belt is not exposed with respect to the polluted member, and a belt support frame which includes a belt support surface to support the endless belt so that the endless belt can be unfolded in the exposed position, and a storing space to store the endless belt so that the endless belt can be folded in the non-exposed position.

Scrapping unit and image forming apparatus having the same, and cleaning methods thereof

An image forming apparatus having a hybrid inkjet head and an inkjet head wiping device includes an array type inkjet head, the first guide part, a carrier, a shuttle type inkjet head, a paper delivery unit, a controller, and a wiping device. The array type inkjet head prints an image onto a printing medium at a stationary state and has the first nozzle unit. The first guide part is spaced apart from the array type inkjet head to dace the array type inkjet head, and the carrier is movably coupled with the first guide part and reciprocates in a width direction of the printing medium. The shuttle type inkjet head has the second nozzle unit and the paper-delivery unit delivers the printing medium to the inkjet heads. The controller controls operations of the inkjet heads and the paper-delivery unit, and the wiping device contacts a surface of the first nozzle unit to wipe out residual ink from the first nozzle unit.
