摘要:
Inside the body of an image forming device, first to fifth electric charge providers are mounted in a first location out of a path of an air flow to the suction unit caused by the action of the suction unit, and a sixth electric charge provider is mounted in a second location through which external air flows in the body caused by the action of the suction unit. Each electric charge provider emits charges in ambient air to cause ultrafine particles floating in the ambient air to clump together.

A hub-based drive coupling mechanism for a fusing assembly, including a gear operatively coupled to a motor; a hub member; and a backup roll having a shaft rotatably coupled to the gear via the hub member, the gear including an outer cylindrical portion having a plurality of tabs disposed along an inner surface thereof, the hub member including an annular portion having a plurality of protrusions radially extending therefrom, and the backup roll shaft having a pin member. The gear rotates for a first fraction of a revolution without rotating the hub member and the backup roll due to the tabs of the gear not contacting the protrusions of the hub member, and rotates for a second fraction of the revolution with the hub member due to contact between the tabs and protrusions, but without rotating the backup roll.

An image forming apparatus (1) is provided. The image forming apparatus includes an image forming unit (20), a door (2) to cover an opening in a chassis (30), a fixing unit, a frame (100), a linear motion member to linearly move along with the door, a guiding member to guide the linear motion member to move linearly, a coupler assembly to couple the door with the linear motion member and move the linear motion member, and a manipulation member being movable according to movement of the linear motion member. The linear motion member includes a contact portion, with which the manipulation member comes in contact along an intersecting direction. The guiding member includes a slider plane to slidably support the linear motion member. The linear motion member is slidably supported by the slider plane of the guiding member at a surface which is on an opposite side from the surface having the contact portion.

An image forming apparatus is provided with a feed interval control section that sets feed intervals of the recording materials, for a defined period from immediately after completion of the warm-up operation for a fixing-side rotor and the pressure-side rotor determined by a warm-up completion determination section, to be longer than feed intervals of the recording materials posterior to the defined period in a high-humidity and low-temperature state. Thereby, the image forming apparatus prevents elongation of a warm-up time while achieving both reduction of the back curl and maintenance of fixability in the high-humidity and low-temperature state.

A fixing device (100) includes a rotatable fixing member (12), a pressing member (13), a drive input rotating body (19A), a first frame (17A; 17B), a support shaft (18C), and at least one positioning member (18A; 18B). The pressing member (13) contacts the fixing member to form a fixing nip therebetween, The drive input rotating body (19A) receives an external driving force and transmits the driving force to the fixing member. The first frame (17A; 17B) supports the fixing member and the pressing member. The support shaft (18C) is provided on the first frame to support the drive input rotating body. At least one positioning member (18A; 18B) is supported by an image forming apparatus body when the fixing device is installed in the image forming apparatus body.
摘要:
Die Erfindung betrifft eine Vorrichtung zum manuellen Öffnen und Schließen eines Gerätegehäuses, insbesondere einer Geräteeinheit eines Vervielfältigungsgerätes mit einem ersten (1) und einem zweiten (2) Gehäuseteil, die mittels einer Schwenkachse (20) verbunden sind und deren eines Gehäuseteil verschwenkbar ist; mit rotierenden Fördermitteln (11;21) in mindestens einer Paar-Anordnung zum Hindurchführen und Transportieren eines Aufzeichnungsmediums (S), die an einem der Schwenkachse gegenüberliegenden Ende der beiden Gehäuseteile in einer aneinander anliegenden achsparallelen Anordnung und in achsparallelen Ausrichtung zur Schwenkachse angeordnet sind, wobei eines der rotierenden Fördermittel im ersten Gehäuseteil und das andere im zweiten Gehäuseteil drehbar, antreibbar und manuell auswechselbar angeordnet sind. Die Vorrichtung weist Mittel zum Verschwenken (3) des ersten Gehäuseteils (1) um die Schwenkachse (20) von einer am zweiten Gehäuseteil (2) anliegenden Schließstellung (CC) zu einer vom zweiten Gehäuseteil entfernten, das Geräteinnere zu Servicezwecken freigebenden Offenstellung (CO); sowie Mittel zum Ent-/Verriegeln (4) des in Schließstellung befindlichen ersten Gehäuseteils von/mit dem zweiten Gehäuseteil; und Mittel zum radialen Trennen/Aneinanderpressen (5) der rotierenden Fördermittel bei entriegelten bzw. verriegelten Gehäuseteilen auf. Zum Erreichen einer Vorrichtung, die die Durchführung eines Geräte-Kundendienstes vereinfacht und erleichtert, insbesondere ein Austauschen von Verschleißteilen vereinfacht und die Behebung einer Störung, wie zum Beispiel eines Transportstaus erleichtert, und zudem einen einfachen, kompakten Aufbau aufweist, ist eine gemeinsame Betätigungseinheit für die Mittel zum Verschwenken (3), Ent-/Verriegeln (4) und Trennen/Aneinanderpressen (5) im Bereich des der Schwenkachse (20) gegenüberliegenden freien Endes der Gehäuseteile (1;2) vorgesehen, mittels der das Ent-/Verriegeln, Verschwenken und Trennen/Anpressen des ersten Gehäuseteils (1) gemeinsam und einhändig in einem einzigen Bewegungsablauf durchführbar ist.
