摘要:
A peripheral unit is controlled by means of a driver in another apparatus, where an instruction sent to the peripheral unit contains both data produced by the driver and data produced by another application in the other apparatus. This is done by subjecting the instruction received from the other apparatus to processing in which the data produced by the other application is deleted.

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.

摘要:
The present invention provides an image forming method for efficiently thermoelectrically transferring and fixing a toner image formed on an electrostatic latent image carrier without scattering of the toner. The image forming method comprises the steps of charging a surface of an electrostatic latent image carrier; exposing the charged surface of the electrostatic latent image carrier to a light beam using optical data corresponding to image data to form a latent image; developing the latent image formed on the surface of the electrostatic latent image carrier with a developer for electrophotography containing a toner for electrophotography to form a toner image; and thermoelectrically transferring the toner image formed on the surface of said electrostatic latent image carrier onto a surface of a recording medium and simultaneously fixing thereon. The toner for electrophotography is comprised of a crystalline polyester resin, the surface temperature of a fixing unit therein is higher by 10° C. or greater than the melting point of said crystalline polyester resin, and the glass transition temperature of the outermost surface layer of the electrostatic latent image carrier is higher by 10° C. or greater than a surface temperature of the fixing unit.
