Abstract: Provided is an inkjet recording apparatus that, regardless of the size of a recording medium, reduces clogging of nozzles by avoiding insufficient flushing, while at the same time avoid a decrease in productivity of the recording medium, and reduces situations in which the recording medium becomes stained due to the staining of opening portions due to ink ejected during flushing. A conveyor belt of the inkjet recording apparatus has a plurality of opening portion groups in a conveying direction of the recording medium in which opening portions for allowing ink ejected from each of the nozzles of the recording head to pass during the flushing are arranged in a belt width direction perpendicular to the conveying direction of the recording medium. A control unit determines a pattern of a plurality of opening portion groups used in flushing in one cycle of the conveyor belt according to the size of the recording medium, and causes the recording medium to be supplied from a recording medium supply unit between the opening portion groups arranged in the conveying direction in the pattern on the conveyor belt.

Abstract: A fixing device includes a fixing member, a pressuring member, a fixing frame, a supporting member and a biasing member. The fixing member and the pressuring member forms a fixing nip. The supporting member has a bearing part which rotatably supports the pressuring member. The biasing member biases the supporting member in a pressing direction in which the pressuring member is made to come into pressure contact with the fixing member. The supporting member has a fulcrum part and a contact part. The fulcrum part is disposed separately from the bearing part and turnably engaged with the fixing frame. The contact part is disposed on an opposite side to the fulcrum part with respect to the bearing part. The fixing frame has a restriction part. The restriction part comes into contact with the contact part to restrict the supporting member from being moved in the pressing direction.

Abstract: An image forming apparatus includes an optical scanning device, a duct, and a cooling fan. The optical scanning device has a rotating polygon mirror, a motor which has a rotating shaft fixed to the rotating polygon mirror, and a housing that accommodates the rotating polygon mirror and the motor. The duct is disposed adjacent to the optical scanning device, and a part of the rotating shaft is exposed into the duct. The cooling fan generates airflow inside the duct. A sectional area of the duct becomes gradually small toward the part of the rotating shaft exposed into the duct from an upstream side of the part of the rotating shaft exposed into the duct with respect to a flow direction of the airflow in the duct, and a sectional area of the duct becomes large at a downstream side of the part of the rotating shaft exposed into the duct.

Abstract: A sheet conveyor device includes a registration roller, an intermediate roller, a first sheet detection section, a first drive controller, a second drive controller, and a third drive controller. The registration roller conveys a sheet toward an image forming section for image formation. The intermediate roller conveys the sheet toward the registration roller. The first sheet detection section is used for optically detecting the sheet between the registration roller and the intermediate roller. The first drive controller drives the intermediate roller, while suspending driving of the registration roller. The second drive controller drives the registration roller when a predetermined conveyance wait period elapses from detection of a sheet by the first sheet detection section. The third drive controller drives the registration roller when a predetermined forced conveyance period elapses from a start of conveyance of the sheet loaded on a sheet loading section.

Abstract: Provided is an inkjet recording apparatus that reduces excessive or insufficient flushing of each of the nozzles by appropriately controlling the ink ejection amount in the next flushing for each nozzle based on the actual ink ejection state of each of the nozzles of a recording head during image formation. A control unit causes the recording head to execute flushing for ejecting the ink at a timing different from a timing that contributes to image formation on the recording medium. A conveyor belt has opening portions for allowing ink ejected from each of the nozzles of the recording head during flushing to pass. The control unit controls the ink ejection amount for each of the nozzles during the next flushing based on an integrated printing rate for each of the nozzles after the recording head has performed the previous flushing.

Abstract: An image forming apparatus includes an ejecting port, an ejected sheet tray and a guiding member. The ejected sheet tray has a sheet stacking face inclined upwardly towards a downstream side from a lower side of the ejecting port. The guiding member is provided at a position on the sheet stacking face to contact with a tip end of the ejected sheet at the position. The guiding member includes a base member attached to the sheet stacking face, a movable guide for stacking the ejected sheet and a biasing member. The movable guide is turnably supported on the base member around a supporting shaft. The biasing member is interposed between the base member and the movable guide at an upstream side from the supporting shaft to bias the movable guide upwardly. The movable guide is turned downwardly against a biasing force of the biasing member by weight of stacked sheets.
