摘要:
An ink jet recording apparatus records by discharging ink from plural recording heads toward a recording medium. Each of the recording heads has a heat pipe mounted thereon, and protruding therefrom so as to have a length which is greater than the recording width of the corresponding recording head. The protruding portions of each heat pipe extending from the recording heads have a heat discharging member attached thereto. That member constitutes a single blower fan for applying an air stream to the heat discharging members corresponding to the recording head, and plural air stream control means for applying the air stream produced by the blower fan to the heat discharging members individually or independently.
摘要:
An ink jet recording apparatus with plural full-line type recording heads has a heat pipe associated with each recording head. The heat pipes are connected together at a common portion in various ways, such as by a heat-conductive block, one or more additional heat pipes or a container with a heat transferring liquid medium. Such an arrangement enables more efficient and compact temperature control of the recording heads.

An image forming apparatus includes reading means for reading the density of a test pattern corresponding to each of plural recording elements of a recording head, the recording elements being arranged in an array, and the test pattern being recorded by the recording elements. An eliminating means eliminates error information, recorded from an area outside a test pattern are, from density information obtained by the reading means when the density of a test pattern end portion corresponding to an end portion of the array of plural of recording elements is determined. A means is provided for uniforming the image densities in correspondence with the plurality of recording elements based on density information from which the error information is eliminated by the eliminating means.

A correction data production apparatus includes a detecting unit for reading a test pattern formed by a recording head having a plurality of recording elements constituting an array, and for detecting a density distribution of a range of the array of the plurality of recording elements, a corresponding unit for causing the density distribution detected by the detecting unit to correspond to the plurality of recording elements on the basis of a reference position where a density of an end portion of the density distribution reaches a predetermined threshold value, a production unit for producing correction data for an image formation density uniforming drive conditions in correspondence with the plurality of recording elements on the basis of the density distribution corresponded by the corresponding unit, and a changing unit for changing the threshold value in accordance with characteristics of the test pattern.
摘要:
An ink jet recording apparatus for performing recording by discharging ink onto a recording medium from a discharging port provided for a recording head comprises a first electrode and a second electrode arranged for attracting unwanted ink discharged from the discharging port, and a power source for applying voltages of opposite polarities to each other to the first electrode and second electrode. This makes it possible to efficiently remove unwanted droplets which are generated at the time of recording, so that more stable and reliable recording can be performed.
摘要:
An ink jet recording apparatus wherein an image is formed on a recording material by ejection of coloring agents having different colors from plural recording heads, the apparatus includes a discriminator for discriminating whether an image having a edge and an image having high image density are to be overlaid or not; and a controller, responsive to the discriminator, for reducing the quantity of the coloring agent for the high density image at a position corresponding to at least one of the edge image and a periphery of the edge image .
摘要:
An ink jet recording apparatus wherein an image is formed on a recording material by ejection of coloring agents having different colors from plural recording heads. The apparatus includes a discriminator for discriminating whether an image having a edge and an image having high image density are to be overlaid or not; and a controller, responsive to the discriminator, for exchanging a primary coloring agent with a secondary coloring agent at a position corresponding to at least one of the edge image and a periphery of the edge image.
