Abstract: An image forming apparatus includes a replaceable member, a first determination unit, and a second determination unit. The replaceable member is removable from the image forming apparatus in an open state of a door and has a storage portion storing given information. The first determination unit determines whether or not a response from the storage portion exists. The second determination unit determines the image forming apparatus is in the open state or a removed state where the replaceable member is removed from the image forming apparatus when the first determination unit determines the response is not exist in given number of times.

Abstract: A releasing device includes: a releasing unit that is made of a resin and disposed on a downstream side in a conveying direction of a recording medium from a fixing portion of a fixing unit which fixes a toner image on the recording medium, the releasing unit releasing the recording medium from the fixing unit; a supporting unit that supports the releasing unit on a supporting face and maintains the releasing unit and the fixing unit in a non-contact state; a screw that is advanced in a direction along the supporting face to secure the releasing unit; and a protruding portion provided between the releasing unit and the supporting unit and disposed at a position in a range extending from a first region between the screw and the supporting face to a second region shifted from the first region in a tightening direction side of the screw.

Abstract: An image forming apparatus includes an image holding body unit having a first supported portion and an image holding body that is rotated while holding an image on a surface of the image holding body; and a conveying unit that is disposed below the image holding body unit and has conveying members for conveying a medium on which the image formed on the surface of the image holding body is to be recorded, image holding body support portions that supports both end portions, in an axial direction, of the image holding body, and a first support portion that supports the first supported portion.

Abstract: An image forming apparatus includes: a rotary body; a rotary body retaining member; pressure members that press the rotary body retaining member along a direction to bring shaft portions of the rotary body into positioning grooves; and an operation member. When an open/shut cover is in an open position, the operation member comes into contact with the rotary body retaining member so as to press the rotary body retaining member in a direction to bring the shaft portions of the rotary body out of the positioning grooves. When the open/shut cover is swung to a close position, the operation member is contacted by the rotary body retaining member pressed by the pressure members, thereby bringing the operation member into contact with part of the apparatus body and keeping the operation member still. The rotary body retaining member and the operation member touch each other through elastic buffering members.

Abstract: An image forming apparatus includes: a medium conveyance unit; an image recording unit; and recording unit support portions. The image recording unit is supported by the medium conveyance unit in an undetachable manner for a user who uses the image forming apparatus. The recording unit support portions have a first support portion and a second support portion which are disposed in the image recording unit on a side of an outlet and are spaced from each other in a width direction of a medium conveyed, and a third support portion which is disposed in the image recording unit on an opposite side to the outlet. At least the first support portion and the second support portion are supported on the side of the outlet of the medium conveyance unit.

Abstract: The present invention provides an image forming apparatus including: a recording medium conveying section; an image forming section, disposed to the recording medium conveying section and relatively moveably supported by the recording medium conveying section at one end side, that forms an image on a recording medium; a side panel that configures a side face portion of the image forming section in a width direction intersecting with the conveying direction, and supports a drive source that drives the image forming section; a support plate, provided between the recording medium conveying section and the image forming section to cover the bottom side of the image forming section, and is supported at a support portion provided at the other end side of the recording medium conveying section; and a resilient member that resiliently supports the support plate and the side panel.

Abstract: An image forming apparatus includes a main body frame; an image formation section contained in the main body frame that forms an image on a recording medium; an ejection mechanism contained in the main body frame that ejects the recording medium on which an image has been formed to an ejection section on the upper surface of the main body frame; an image scanning device mounted on the ejection section that scans the image of a document; and an operation section provided on the upstream side in the ejection direction of the recording medium in the ejection section that operates the image scanning device; wherein sides and the backside of the ejection section being opened viewed from the operation section side.
