  • Patent number: 8843009
    Abstract: An image forming apparatus includes an image forming mechanism, an image bearing member, a transfer member, a transfer member mount, and an image detector. The image forming mechanism forms a first image and a second image on a surface of the image bearing member. The transfer member is disposed facing the image bearing member and contactable thereagainst to form a transfer nip at which the first image is transferred from the image bearing member to a recording medium. The transfer member mount on which the transfer member is disposed accommodates multiple different sizes of transfer member. The image detector detects the second image on the surface of the image bearing member. The image forming apparatus includes a plurality of interchangeable transfer members, only one of which at any given time faces the image bearing member, and a transfer member switching device to switch between the plurality of transfer members.

  • Patent number: 8639173
    Abstract: A pressing mechanism that presses a solid lubricant against a brush roller includes two movable members that receive the biasing force of a single biasing unit, rotate around a fulcrum, and press places of the solid lubricant at the symmetric positions with respect to the center of a contact portion of the solid lubricant. The curvature of a portion of a curve shape of the movable member that contacts a casing inner wall is set such that the pressing force in a pressing direction of the solid lubricant in the last stage becomes greater than the pressing force in an intermediate stage, from the initial stage to the last stage after the solid lubricant of the predetermined amount or more is scraped off via the intermediate stage.

  • Patent number: 8472856
    Abstract: An image forming apparatus includes a plurality of image forming units that are arranged in parallel so as to be opposed to an intermediate transfer belt or a transfer carriage belt. A black image forming unit that forms a black toner image is arranged at a downstream end or upstream end in the running direction of the intermediate transfer belt or the transfer carriage belt with respect to the other image forming units. The black image forming unit is configured so that its lubricant supplying unit contains a larger amount of lubricant.

  • Publication number: 20120237251
    Abstract: An image forming apparatus includes an image bearing member to bear a toner image on a surface thereof, an intermediate transfer member disposed facing the image bearing member, onto which the toner image is transferred, a primary transfer device disposed opposite the image bearing member with the intermediate transfer member interposed therebetween to transfer the toner image from the image bearing member onto the intermediate transfer member, a cleaning device detachably attachable relative to the intermediate transfer member and including a cleaning member to contact the surface of the intermediate transfer member to remove residual toner remaining on the intermediate transfer member after transfer of the toner image, and a lubricant application device detachably attachable relative to the intermediate transfer device to apply a lubricant on the surface of the intermediate transfer member. The cleaning device and the lubricant application device are detachably attachable independent of each other.

  • Patent number: 8169645
    Abstract: A printer includes a data obtaining unit, a storage unit, an engine, and a printing unit. The data obtaining unit obtains, from print data stored in the storage unit, print data for sheets less than the maximum number of sheets dischargeable to a discharge tray as target print data and sends the target print data to the engine via the printing unit. The target print data includes first print data of odd pages and second print data of even pages. After printing the first print data on one side of sheets fed from a feed tray and discharges the sheets onto the discharge tray, the engine prints the second print data on the other side of the sheets manually returned from the discharge tray to the feed tray.

  • Patent number: 8089484
    Abstract: Displayed on a first LCD 11 are a “fire” planet 40a, a “wood” planet 40b; an “earth” planet 40c, a “wind” planet 40d and a “water” planet 40e, each traveling along an orbit by a unique orbital period. While an attribute symbol is traveling through an active zone that is associated with the attribute symbol, the status of the attribute represented by the attribute symbol is active. An attribute being active affects the space attribute, which is the attribute of a particular space in the game world. The space attribute affects the ability parameters of characters of the same attribute. Thus, it is possible to enrich the strategic aspect of a video game using characters' attributes.

  • Patent number: 7885551
    Abstract: A terminal apparatus, a consumables residual quantity display program, and a recording medium are disclosed. The terminal apparatus, which is connected to a printing apparatus through a network, includes an acquisition unit for acquiring information about consumables of the printing apparatus from the printing apparatus; and a display controller for displaying the information about the consumables, which information is acquired by the acquisition unit, if the information of at least one item of the consumables fulfills a predetermined condition. The display controller may display a no-display specifying screen that prompts a user to specify whether a “no-display” mode should be activated, in which “no-display” mode, displaying the information about the consumables is stopped even if the predetermined condition is fulfilled when the information is to be acquired by the acquisition unit at a next time.
