    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.

    摘要： Provided are an image forming apparatus and an image forming method capable of easily forming an output image having desired gradation characteristics and capable of reducing running cost. In an intermediate transfer-type image forming apparatus, an image forming section is configured by including a first image forming section which forms a color toner image on a photoconductor, and a second image forming section which is located on the upstream side of the first image forming section and forms a transparent toner image on the photoconductor. Further, after the transparent toner image is formed on an intermediate transfer member by the second image forming section, the first image forming section forms, on the basis of image data (correction gradation values) corrected by a gradation correcting section, a color toner image so that the color toner image is superimposed on the transparent toner image.
