Abstract: A recording head and a recording unit in which both reliability for ejection stability and storage stability and suppression of color mixing phenomenon can be satisfied. The recording head has ejection opening arrays for ejecting a plurality of inks constituting an ink set, respectively. The inks are respectively contained in an ink cartridge having an ink containing section which is brought into an enclosed state. Among the plurality of inks, specific gravities of at least three inks are different from one another and the difference in specific gravity of at least two inks is 0.020 or more. The ejection opening arrays are arranged such that the total sum of the differences in specific gravity between each two inks ejected from adjoining ejection opening arrays among the inks ejected from the ejection opening arrays is minimized.

Abstract: Disclosed is an aqueous ink comprising at least water, a plurality of water-soluble organic solvents and a coloring material. The coloring material is a pigment, and, it contains a pigment particle having at least one ionic group bonded to a surface of the pigment particle directly or via another atomic group. The plurality of water-soluble organic solvents have a good medium or good mediums for the pigment and a poor medium or poor mediums for the pigment. The poor medium does not solvate perfectly or substantially the pigment. The ionic group undergoes perfectly or substantially no ionic dissociation in the poor medium. Also, among the respective Ka values of the plurality of water-soluble organic solvents as determined by the Bristow method, the Ka value of the poor medium is maximum.

Abstract: The present invention aims to provide an ink which has a sufficiently large area factor even in a small ink droplet quantity and can obtain images having a high image density, and further has a superior storage stability. According to the present invention, a cyan ink is provided which is used in an ink set having four kinds of aqueous inks consisting of a cyan ink, a magenta ink, a yellow ink and a black ink in which each ink comprises at least water, a water-insoluble coloring material, and a plurality of water-soluble organic solvents having a good medium or good mediums for the water-insoluble coloring material and a poor medium or poor mediums for the water-insoluble coloring material, wherein, the ratio B 1 /A 1 is from 0.5 or more to 3.0 or less, where A 1 denotes the total content (mass%) of the good medium based on the total mass of the cyan ink and B 1 denotes the total content (mass%) of the poor medium based on the total mass of the cyan ink, and a water-soluble organic solvent which shows the maximum Ka value among the respective Ka values of the plurality of water-soluble organic solvents as determined by the Bristow method is the poor medium.

Abstract: An image recording apparatus includes a FAX unit (1) and a printer unit (2). The printer unit (2) has an ink-jet printing head (205), and records an image in accordance with image data received by the FAX unit (1). In this apparatus, when the power supply is turned on, the printer unit (2) performs a hard power-ON initialization process to initialize a watch-dog timer, registers, the work area of a RAM, and the like, and also initializes the RAM to erase data left in buffers. Thereafter, the printer unit transfers to a standby state. When a print request or a printer setting request is generated in the standby state, a soft power supply initialization process is executed to perform checking of the RAM, initialization of the work area, and initialization of carriage control and paper feed control, and the like. In the standby state, LEDs and the like of the printer unit are kept OFF. An operation error of the printer unit caused by remaining data can be prevented, and reliability of the apparatus can be improved. In addition, unnecessary power consumption can be prevented.
