    摘要： Problem: To provide a microencapsulated color material for an ink composition which is excellent in dispersion stability, ejection stability and color developability, excellent in fastness and rubbing resistance of images, and hard to cause blurs of images, and can provide recorded matter having high print density; an ink composition using the color material; a production process thereof; an ink jet recording process; recorded matter; and microencapsulated matter.Means for Resolution: A surface of a core material including color material particles such as a pigment is covered with a wall material mainly comprising: 1) a polymer (A) having an ionic group and a hydrophobic group; and 2) a polymer (B) having at least; repeating structural units derived from a first polymerizable surfactant having an ionic group with a charge opposite to the charge of the ionic group of the polymer, a hydrophobic group and a polymerizable group; and repeating structural units derived from a second polymerizable surfactant having a charge of the same kind as or opposite to the charge of the first polymerizable surfactant, and/or a hydrophilic monomer having a charge of the same kind as or opposite to the charge of the ionic group of the polymer and/or a hydrophobic monomer, thereby performing microencapsulation. The color material particles such as the pigment are used as the core material, and a color material obtained by microencapsulating them is allowed to be contained in an aqueous medium to form an ink composition, which is ejected from an ink head onto a recording medium by an ink jet recording process, thereby obtaining recorded matter. By constituting the core material by a pharmaceutical preparation, a metal powder, a ceramic or the like, surface modification of the core material becomes possible.

    摘要： Image forming apparatus (100) creates a toner pattern on intermediate transfer belt (11) as a preprocessing of gradation correction, and calculates a cycle at which density unevenness is largest. Then, a toner image for gradation correction is formed so as to cancel cyclic unevenness at a cycle at which the largest density unevenness occurs. As a result of this, it becomes possible to suppress the deterioration of density detection accuracy and perform a highly accurate gradation correction even if density unevenness of any cycle occurs.

    摘要： According to one embodiment, a magnetic data system includes a magnetic disk medium, a magnetic head having a writer element and/or a reader element, an exothermic resistor element for thermal fly-height control (TFC), a contact detection sensor having a resistor element and at least one contact detection electrode, and an insulating film on a medium facing side of the magnetic head to protect the contact detection sensor, the insulating film having a thickness greater than the contact detection electrode, a drive mechanism for passing the magnetic disk medium over the magnetic head, and a controller electrically coupled to the magnetic head for controlling operation of the magnetic head, wherein the controller adjusts magnetic spacing between the magnetic head and the magnetic disk medium via thermal distortion of the exothermic resistor element. The contact detection sensor may be used as a second TFC resistor element.
