Abstract:
An image forming apparatus which forms an image on a recording sheet includes a housing having an exhaust outlet and an image forming unit disposed in the housing and configured to form an image on a recording sheet. A duct in the housing may have an inlet at a first end in the housing, and communicate with the exhaust outlet at a second end in the housing. The image forming apparatus includes an exhaust fan disposed between the exhaust outlet and the duct, and being configured to cause air entering the duct from the inlet to go toward the exhaust outlet; a first filter disposed in the duct to cover the inlet and being configured to remove dust suspended in the air, and a second filter disposed in the duct downstream from the first filter in a direction of airflow and being configured to remove dust suspended in the air.
Abstract:
The image-forming device includes an image-forming unit, a fixing unit, a pair of first guides, and a pair of second guides. The recording sheet defines a width in a direction perpendicular to a sheet conveying direction. The image-forming unit forms a developing agent image on the recording sheet. The fixing unit includes a heating and a pressure roller. The heating roller heats the recording sheet discharged from the image-forming unit. The pressure roller presses the recording sheet against the heating roller. The heating roller and the pressure roller provide a nip point where the recording sheet is nipped therebetween. The nip point is offset in a thickness direction of the recording sheet from a plane along which the recording sheet is discharged from the image-forming unit. A sheet conveying path is provided from the image-forming unit to the fixing unit. The pair of first guides dispose on the conveying path and configure to contact with an image-forming side of the recording sheet at both widthwise edges thereof, for restraining the recording sheet from being displaced toward the image-forming side. The pair of second guides dispose on the conveying path and configure to contact with the image-forming side of the recording sheet at both widthwise edges thereof for restraining the recording sheet from being displaced toward the image-forming side, a distance between the pair of first guides in the widthwise direction being greater than a distance between the pair of second guides in the widthwise direction, and the pair of second guides being offset from the pair of first guides in the sheet conveying direction.
Abstract:
An image forming apparatus includes a driving source, a supply roller which supplies a recording sheet, a fixing device, a fixing driving gear mechanism which transmits a driving force of the driving source to the fixing device, a supply driving gear mechanism which transmits the driving force to the supply roller, and a control device. The control device controls the driving source to rotate in one direction when a temperature of the fixing device exceeds a predetermined temperature, and to rotate in a reverse direction when the temperature is the predetermined temperature or lower. The fixing driving gear mechanism includes a mechanism which interrupts a transmission of the driving force when rotating in the reverse direction. The supply driving gear mechanism includes a mechanism which causes a rotating direction of the supply roller to be the same when the driving source rotates in both directions.
Abstract:
An image forming apparatus includes gears for driving a first photosensitive drum and a second photosensitive drum. The gears includes a first drum gear, a second drum gear, and a first drive gear configured to apply a rotational force to the first drum gear and the second drum gear by meshing with the first drum gear and the second drum gear. Specific positional relations among the first photosensitive drum, the second photosensitive drum, the first drum gear, the second drum gear, and the first drive gear are configured based on exposure positions and transfer position. Such an image forming apparatus may reduce an occurrence of an image formation failure even when the dimensional unevenness of the gears occurs.
