Abstract: An image forming apparatus has an openable-closable member, an image carrier, a cover sheet, and a cover moving mechanism. The openable-closable member is arranged in an open position where it keeps a recording medium conveying passage open and in a closed position where it keeps the recording medium conveying passage closed. The cover sheet is reciprocatable between a protection position where it covers the recording medium conveying passage side of the image carrier and a retracted position where it is retracted from the recording medium conveying passage. The cover moving mechanism moves the cover sheet to the retracted position or to the protection position by opening and closing the openable-closable member. Drawing out the cover sheet in the protection position to the recording medium conveying passage side causes the cover sheet to be arranged in a recording medium removal position.

Abstract: A charging device includes a charging member, a cleaning member, and a bearing. The charging member charges an image carrier. The cleaning member cleans the charging member. The bearing includes a first bearing part and a second bearing part. The first bearing part rotatably supports the charging member. The second bearing part rotatably supports the cleaning member and is divided from the first bearing part. The first bearing part is movable between a first contact position to make the charging member come into contact with the image carrier and a first separating position to make the charging member separate from the image carrier. The second bearing part is movable between a second contact position to make the cleaning member come into contact with the charging member and a second separating position to make the cleaning member separate from the charging member.

Abstract: An image forming apparatus includes a sheet storing cassette, a lift mechanism, a sheet feeding portion, a remaining quantity sensing portion, and a control portion. The control portion, during continuous sheet feeding by the sheet feeding portion, controls the lift mechanism to make a sheet stacking plate ascend to a lifted position where sheets make contact with the sheet feeding portion, and feeds a foregoing sheet and then, at a sheet feeding timing a predetermined time thereafter, starts feeding the following sheet. The control portion makes the sheet feeding timing earlier as the remaining quantity of the sheets sensed by the remaining quantity sensing portion decreases.

Abstract: An image forming device includes a sheet transport portion; an image forming portion; and a sheet conveying portion. The sheet conveying portion includes: a guide plate extending in a sheet width direction; a plurality of guide ribs arranged on the guide plate along the sheet width direction and extending along the sheet convey direction, each having a sheet guide surface guiding the sheet being conveyed; and a suction portion which causes suction air to act on a sheet guided by the guide ribs to bring the sheet into close contact with the sheet guide surface via suction holes opened in the guide plate and which is configured to reduce an air amount of the suction air in regions of the guide ribs on the downstream side in the sheet convey direction to be smaller than that in regions of the guide ribs on an upstream side.

Abstract: An image forming apparatus includes an image carrier, a developing device, a transfer section, a main body frame, a fixing device, a discharge section, a recording medium conveyance path, an openable/closable member, a cover sheet, a cover moving mechanism, a cooling section, and a slide member. The cover sheet is reciprocatable between a protection position at which it covers a side of the image carrier that faces the recording medium conveyance path and a retraction position at which it is arranged in a clearance between the image carrier and the main body frame. At the retraction position, the cover sheet blocks an air flow passage between the cooling section and the fixing device. The slide member is disposed at a lower end corner portion of the main body frame, and contacts the cover sheet reciprocating between the protection position and the retraction position.

Abstract: A sheet feeding device (1) includes a cassette (10), size detector (60), and attachment detector (30). The size detector (60) detects the size of sheets in the cassette (10). The size detector (60) includes an interlocking member (61) and switch unit (81). The interlocking member (61) includes size-detection target portions (64) and slides to sliding of a regulating member (11). The switch unit (81) detects a position of the regulating member (11) based on a state of the switches (82) that detect the size-detection target portions (64). The attachment detector (30) includes an attachment-detection target member (31) and attachment detecting member (41). The attachment detecting member (41) detects the attachment-detection target member (31) in response to attachment of the cassette (10). The controller (70) detects the sheet size based on a state of the switch unit (81) in response to the attachment detector (30) detecting attachment of the cassette (10).

Abstract: A sheet feed cassette includes a bottom portion, a first cursor, a second cursor, and a fixing rack. The second cursor includes a regulating member, a lock member, and a biasing member. The regulating member abuts on the rear end edge of the sheet to regulate a position of the sheet in the mounting direction. The lock member includes a shaft portion extending in a direction intersecting with the mounting direction and an engaging protrusion located below the shaft portion. The biasing member is located and compressed between the regulating member and the lock member above the shaft portion. The gear teeth of the fixing rack and the engaging protrusion of the lock member engage so as to lock a position of the second cursor in the mounting direction. The regulating member and the lock member are separated above the shaft portion in the locked state.
