摘要： A sheet stacking device includes: an evacuation section for transporting and ejecting sheets; a sheet exit tray for stacking the ejected sheets; an arm supporting member; and a sheet presser arm including a supported end at one end, a free end at the other end which is capable of pressing the sheets stacked on the sheet exit tray directly or via a contact member attached to the free end, and a flexure portion having flexibility between the supported end and the free end. The supported end is attached to the arm supporting member. The arm can apply, by the flexibility of the flexure portion, a pressing force to the sheets stacked on the sheet exit tray and a repulsive force to each of the ejected sheets when a front end of the ejected sheet strikes against the arm.

摘要： A cleaning unit includes a cabinet, a cleaning blade, a toner drop preventive sheet, and an auxiliary member. The cabinet has an opening facing an outer periphery of a photosensitive drum. The cleaning blade is operative to scrape down residual toner adhering to the outer periphery of the photosensitive drum. The toner drop preventive sheet is operative to prevent the residual toner scraped down by the cleaning blade from dropping between the photosensitive drum and the cabinet. The auxiliary member is disposed below the toner drop preventive sheet and is movable between a first position for receiving a bulk substance dropping from the toner drop preventive sheet and a second position for dropping the bulk substance received from the toner drop preventive sheet.

摘要： A belt carrying device includes supporting rollers, an endless belt supported by the supporting rollers, and guiding members provided on the endless belt. The endless belt is rotated by rotation of the supporting rollers. An outer peripheral surface of the endless belt is in contact with a cleaning member. The guiding members are provided on those projecting areas of the endless belt, which project in an axial direction of the supporting rollers from both end surfaces of the supporting roller. A guiding member suppresses meandering of the endless belt by coming into contact with an end surface of the supporting roller. Formed on the end, surfaces of at least one of the supporting rollers are projecting sections and groove sections, which are rotated around a rotation axis of the at least one of the supporting rollers in response to rotation of the at least one of the supporting rollers.

摘要： A secondary transfer unit stretches a transfer belt in an endless form over a driving roller, a driven roller, a transfer roller, an auxiliary roller, and a support roller therebetween. The transfer belt moves, by rotation of the driving roller, along a circulation path which passes through a transfer position. The transfer roller and the auxiliary roller press the transfer belt from the inner peripheral surface of the transfer belt toward an intermediate transfer belt in the transfer position. The transfer belt has an outer peripheral surface thereof which is pressed against the intermediate transfer belt and is roughened so that the surface roughness of the outer peripheral surface becomes 6 μm to 10 μm.

摘要： A transfer device includes a transfer belt, a transfer roller and a tension roller over which the transfer belt is passed in a tensioned condition and which is made to be in an electrically floated state; it also includes a guide member that is installed in the vicinity of the tension roller. A control section, in transfer processing, controls a first switch so that the guide member is in a grounded state while controlling a second switch so that an electric current being caused to flow to the transfer roller becomes a first electric current; and in cleaning processing, controls the first switch so that the guide member is in an electrically floated state while controlling the second switch so that an electric current being caused to flow to the transfer roller becomes a second electric current.

摘要： When a print request has been made, a control portion confirms whether or not there is a request for post-processing by a paper post-processing portion (step S2) and the type of recording paper that is to be used (step S8). If there is a request for post-processing, then it is determined whether or not a discharge tray is extended (step S3). If the result shows that the discharge tray is retracted, then a message urging the discharge tray to be extended is displayed on a liquid crystal display panel (step S6), and if the discharge tray is extended, then print processing is started (step S4). Furthermore, if the size of recording paper that is to be used is longer than the discharge tray in a retracted state, then a message urging the discharge tray to be extended is displayed on the liquid crystal display panel (step S6), and if the discharge tray is extended, then print processing is started (step S4).
