An image forming apparatus for forming an image on a recording medium is disclosed. The image forming apparatus includes a print head () having an ink emitting surface () in which there are formed a plural number of ink emitting openings (). An ink is emitted from the ink emitting openings () for forming an image on a recording medium. The image forming apparatus also includes an emission controller () for controlling the ink emission from the ink emitting openings () formed in the ink emitting surface (). The emission controller () is responsive to an input image signal to control the quantity of preliminary ink emission from one or more of the ink emitting openings () or to select one or more of the ink emitting openings (). In this manner, the quantity of the preliminary ink emission from the ink emitting openings () is controlled, or one or more of the ink emitting openings () is selected, responsive to the image signal, to diminish the wasteful ink emission and to clean the ink emitting openings () or the vicinity without damaging the ink emitting surface ().

Image forming apparatus and controlling method therefor

A printer is provided which sprays ink from nozzles to print recording paper P. It includes a paper feed/delivery mechanism () to carrying the paper P to which the ink is to adhere, nozzles () to spray the ink as droplets, an ink-spraying head () to spray the ink from the nozzles toward the paper P having been carried to a position opposite to the nozzles, an ink-spraying controller () to control the ink-spraying head () to spray the ink from the nozzles in predetermined timing, a temperature sensor () to detect the ambient temperature and/or humidity when spraying the ink from the nozzles, a speed discrimination unit () to judge whether the carrying speed of the paper P has been changed, a memory () having stored therein ink-spraying control data intended for controlling the spraying timing correspondingly to the type of the paper P, and a controller () to delay, when the carrying speed of the paper P has been increased in the process of printing, the timing of spraying ink in other color than black based on the temperature detected by the temperature sensor and ink-spraying control data for the type of the paper P, pre-stored in the memory, in relation to that which is before the carrying speed of the paper P is increased, thereby projecting the other ink than the black ink to a position to which the black ink is to be projected.
