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: 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.

Abstract: PROBLEM TO BE SOLVED: To provide an image reader that has high productivity and can be made compact, and to provide its control method, a control program and a storage medium. SOLUTION: A movable image sensor for reading an original is moved to a home position (S302), if a read image at the home position is entirely a white image (S304), an image is read while moving the image sensor (S306 to S308), and a position obtained by moving the image sensor from a position where the entire black image is read by a prescribed distance (e) is defined as a new home position (S311).

Abstract: PROBLEM TO BE SOLVED: To provide an image reader, its control method, a control program, and a storage medium that can simplify the control and enhance the productivity. SOLUTION: An original is set in a copy mode, after number of copies, density and resolution or the like are entered, when a start key is depressed, copying is started (S603). When an original sensor is set ON (S604), the reader judges that copying by an ADF is considered, and the copying continues until all originals set on the ADF are copied by a designated number of copies (S605). When the original sensor is set OFF after the depression of the start key, the reader judges that the user considers copying on a flat bed, the reader repeats copying until execution of a designated number of copies is judged (S608).

Abstract: PROBLEM TO BE SOLVED: To provide an image forming apparatus, a copy control method, a storage medium, and a program, which can reduce cost by eliminating the need for a memory with a large capacity and attain color copying with high image quality. SOLUTION: A CPU 101 of the image forming apparatus executes memory copying by using compression in the case of a sheet read mode where an original is read and discharged while the original is being carried, or executes multi- reading or storage of print data of a first copy to an image memory 104 and executes copying of the print data stored in the image memory 104 at recording of second and succeeding data in a book read mode where the original is read while the original is fixed on the basis of a control program stored in a ROM 102, when a plurality of copies are made from one original.
