An image forming apparatus includes an image forming unit configured to form an image on a transfer-receiving member conveyed from a first side to a second side, and a fixing device disposed on a side of the image forming unit closer to the second side, and configured to fix the image formed on the transfer-receiving member. A conveying path formation member is configured to form a conveying path along which the transfer-receiving member is conveyed from the image forming unit to the fixing device. The conveying path formation member includes a first member having first through holes in the up-down direction, and a second member having second through holes in the up-down direction, wherein the second member faces the first member such that the second through holes do not overlap the first through holes when projected in the up-down direction.

A recording medium discharging apparatus which can be mounted on top of the image forming apparatus includes a plurality of recording medium storers and a locking mechanism for locking the discharging apparatus to the image forming apparatus when the discharging apparatus is mounted on the image forming apparatus. The locking mechanism includes a release lever for unlocking the discharging apparatus by being manipulated to shift in the same direction as the discharging apparatus moves away from the image forming apparatus to be dismounted from it. The locking mechanism prevents the discharging apparatus from falling off the image forming apparatus even if external force is applied to the discharging apparatus mounted on the image forming apparatus. The release lever for unlocking the discharging apparatus makes it easy to dismount the discharging apparatus from the image forming apparatus.

An image reading apparatus including an wall disposed on a first side of the image reading apparatus in a width direction orthogonal to a conveyance direction of a sheet is provided. The wall extends in a direction orthogonal to the width direction. The image reading apparatus further includes a first driven roller disposed on a second side in the width direction relative to the wall; a first driving roller opposed to the first driven roller; a first driven shaft inserted into the first driven roller and urged against the first driving roller; a second driven roller disposed on the second side relative to the first driven roller; a second driving roller opposed to the second driven roller; a second driven shaft inserted into the second driven roller and urged against the second driving roller; and a reader unit configured to read the image on the sheet.

An image forming apparatus, such as a printer, may have a horizontally-loaded drawer containing, for example, a toner cartridge or an image forming unit having toner. The apparatus may have an opening through which the drawer is inserted, and a cover over the opening. The cover may include two or more protrusions to assist in forcing the drawer into place as the cover is closed. The cover may include a first protrusion that is closer to the cover's hinge, and a second that is farther from the hinge than the first. The first protrusion may also be longer, extending further from the cover, than the second, so that during the closing operation, the first protrusion makes contact with the drawer before the second. The points of contact on the drawer may be angled and/or curved such that the force exerted by the protrusions directs the drawer horizontally and, if desired, downwardly towards an operating position. A protrusion may be aligned such that, when the cover is in the closed position, the protrusion is offset from a point of contact on the drawer, and exerts no horizontal force on the drawer.

A front cover and an upper panel of the image forming device is engaged with each other by an engagement mechanism. The engagement mechanism includes a claw and an engagement member that engages with the claw. The claw is disposed on an upper section of the front cover, and the engagement member is disposed on the upper panel. The engagement mechanism further includes surfaces of the front cover and ribs that abut the surfaces. The ribs are provided to the upper section of the front cover and protrude in a direction perpendicular to a direction in which the front cover is opened and closed.

A laser printer for forming toner images on sheets includes a duct wall and a shutter. The duct wall extends between a process cartridge, which is filled with toner, and a thermal fixing unit, which generates heat to fix toner images onto the sheets. The duct wall defines a duct and is formed with openings at its side that faces the thermal fixing unit. A fan is provided for drawing hot air from the thermal fixing unit, through the openings in the duct wall and the duct itself, and out from the laser printer. The shutter moves in and out of contact with the process cartridge in association with opening and closing movement of a cover of the laser printer. When the shutter is in contact with the process cartridge, an exhaust chamber is formed that connects an ozone exhaust hole of the process cartridge with the duct. Another fan is provided for drawing the ozone generated by a charge unit of the process cartridge through the ozone exhaust hole, the exhaust chamber, and the duct.

A sheet feeding device to feed a sheet in a sheet feeding path is provided. The sheet feeding device includes a plurality of feeding rollers to feed a sheet in the sheet feeding path, and a dust remover unit to remove dust adhered onto a surface of the sheet. The dust remover unit includes a dust absorber roller to absorb dust from a surface of the sheet, a dust remover member arranged to be in contact with a surface of the dust absorber roller to remove the dust from the surface of the dust absorber roller, a conveyer member, arranged to be opposed to the dust remover member, to convey the dust removed by the dust remover member, and a cutter member, arranged in an intervening position between the dust remover roller and the conveyer member, to cut the dust removed by the dust remover member into smaller pieces.
