摘要:
An ink jet recording apparatus, for effecting recording on a recording material by ejecting a plurality of inks with relative scanning movement between a recording head and the recording material, includes an obtaining unit for obtaining relative information indicative of a relative relation between the amounts of inks to be ejected for each of unit areas provided by dividing an area in the neighborhood of a boundary between adjacent bands of scanning recording of the recording head across the recording material; a determining unit for determining, for each of the inks, a reduction rate at which the amount of the ink to be ejected to the neighborhood of the boundary in the unit area on the basis of the relative information for each of the unit areas obtained by the obtaining unit and on the basis of quantity information indicative of an amount of each into be ejected in the unit area; and a reducing unit for reducing the amount of each ink to be ejected to the neighborhood of the boundary on the basis of the reduction rate for each ink determined by the determining unit.

An ink-jet recording apparatus applicable for two-side recording, which permits reliable reduction of smears caused by contact of the recording medium or secondary smears staining the following recording media by the ink adhering in the conveyance path, and obtaining high-quality images. After performing recording on the surface of the recording medium by the recording head for discharging ink, the recording medium is reversed for recording on the back thereof. For each of unit regions obtained by dividing the region corresponding to the surface of the recording medium, information about the quantity of ink to be applied to these unit regions is acquired, and the length of the operation downtime corresponding to the period of time from the end of the operation relating to recording on the surface of the recording medium up to the operation start relating to recording on the back of the recording medium is determined based on the acquired information.

An ink jet printing apparatus is provided which can prevent a discharged paper-induced smear efficiently with a simple construction. To achieve this objective, the ink jet printing apparatus of this invention determines, based on an amount of ink ejected per unit area onto a preceding print medium last discharged to the discharge position by the discharging section, a required time duration that needs to elapse before a subsequent print medium being discharged toward the discharge position is allowed to contact a predetermined area of the preceding print medium and then controls a printing speed on the subsequent print medium so that the subsequent print medium will not contact the predetermined area of the preceding print medium within the time duration determined.

An ink printer for printing on a recording medium using a liquid ink includes at least one rotatable member arranged in a region of a transport path of the recording medium. The rotatable member is located so as to be capable of contacting liquid ink for forming an image on the recording medium. The rotatable member includes a radially outermost perimeter portion which serves as a recording medium contacting peripheral surface. The outermost perimeter portion has an outermost edge which is continuously contactable with the printing surface of the recording medium. The bonding force with respect to the ink on the outermost edge is less than the sum of a bonding force between the recording medium and the ink on a surface of the recording medium, and the cohesive force of the ink itself on the surface of the recording medium. As a result adherence of the ink to the contacting peripheral surface of the at least one rotatable member is prevented.

An ink jet recording apparatus includes ink ejecting outlets for ejecting ink, an ink container for containing the ink to be supplied to the ejecting outlets, ink supply passage for supplying the ink from the container to the ejecting outlets, a recovery system for forcedly ejecting the ink through the ejecting outlets. The recovery system repeats the forced ejecting action, and a quantity of the ink ejected by one forced ejecting action is larger than an inside volume of the ink supply passage.
