摘要： A sheet feeding device includes a feeding tray, a conveying device, an ejecting tray, a feeding guide and a conveying rib. On the feeding tray, a sheet is placed. The conveying device feeds the sheet on the feeding tray to an image reading device. The ejecting tray receives the sheet after image reading. The feeding guide is configured to be movable in a direction intersecting a feeding direction of the sheet and to regulate a position in a width direction of the sheet on the feeding tray. The conveying rib is configured to be movable in interlocking with movement of the feeding guide and to lead the sheet to be ejected onto the ejecting tray.

摘要： An image forming apparatus includes a plurality of image carrying members, an intermediate transfer belt, a plurality of rollers, and a correcting mechanism. The intermediate transfer belt is endless and, to it, toner images formed on the image carrying members respectively are transferred by being sequentially superposed on each other. The correction mechanism includes a slanted bearing, which rotatably supports a tension roller, and a main body guide roller, which makes contact with the slanted bearing when it moves as a result of the intermediate transfer belt meandering and which moves the slanted bearing along with one end of the tension roller in the axial direction in the direction perpendicular to the axial direction to correct meandering of the intermediate transfer belt with respect to the tension roller. The main body guide roller is a rotary member which rotates while in contact with the slanted bearing.

摘要： An image reading apparatus (6) includes a document placing table (6a) to an upper surface of which a contact glass (25) is fixed, and a document pressing device (24) supported at an end of the document placing table (6a) to be openable/closable via a hinge portion, and having, on its back surface side, a document presser (30) that presses a document placed on the contact glass (25). The document pressing device (24) includes a light transmission window (31) transmitting light in a front-surface-to-back-surface direction of the document pressing device (24). The light transmission window (31) is disposed at a position not overlapping with the contact glass (25) when the document pressing device (24) is at the closure position, and when the document pressing device (24) has moved in an opening direction from the closure position, light that has passed through the light transmission window (31) reaches the contact glass (25).

摘要： An image forming apparatus includes a fixing unit, a first support portion, and a second support portion. First support portion fits with and positions first supported portion, which is end of fixing unit, in up-down direction and supports first supported portion movably in insertion direction of fixing unit toward attachment position. Second support portion fits with and positions second supported portion, which is another end of fixing unit, in up-down direction and supports second supported portion movably in insertion direction. Height adjustment portion adjusts height position of fixing unit by moving second support portion in up-down direction. The first support portion includes vertical surface facing first supported portion and extending in up-down direction, and vertical surface has projection at an end thereof on foreside of insertion direction, the projection projecting from the vertical surface in first direction of going away from the vertical surface.

摘要： An intermediate transfer device includes an intermediate transfer belt, a plurality of primary transfer rollers, a plurality of pairs of support members, a biasing member, a pair of movable members, and a pair of frame members. The plurality of pairs of support members rotatably support both end parts of respective rotary shafts of the plurality of primary transfer rollers and are pivotable in directions in which the primary transfer rollers approach and separate from the intermediate transfer belt. The pair of movable members makes contact with the support members on both end sides of the rotary shafts of the plurality of primary transfer rollers so as to cause the support members to pivot. In a rotation axis direction of the primary transfer rollers, the movable members are disposed between the pair of frame members and within an extending range of the intermediate transfer belt.

摘要： A driving device includes shaft, support member, restraining member, and connection portion. Shaft has a screw portion formed on an outer peripheral surface thereof. Support member rotatably supports shaft. Restraining member restrains shaft so as not to be movable in an axial direction thereof. Connection portion is formed in one end portion of shaft, and has output-side joint member detachably connected thereto. Input-side joint member is engaged by thread with screw portion of shaft so as to be rotatably supported. By being driven to rotate by drive source, input-side joint member is movable between connection position where input-side joint member is connected to output-side joint member and withdrawal position where connection is cut off. Driving device includes compression spring. When input-side joint member is moved from withdrawal position to connection position by drive source, compression spring compressively deform, while being sandwiched by input-side joint member and output-side joint member.
