A liquid discharge apparatus includes an apparatus body, a holder, a stage, an exhaust fan, a suction port, and a partition. The holder holds a target object. The stage reciprocates while holding the holder that holds the target object. The exhaust fan generates an airflow. The suction port is disposed on a side portion of the holder to suck the airflow generated by the exhaust fan. The partition partitions an interior of the apparatus body into a space including the suction port and a space not including the suction port. The partition and the holder are arranged to form an airflow path toward the suction port between the partition and the holder.

Liquid discharge apparatus

A heating apparatus includes an apparatus body, a receiver, a heating device, and a partition. The receiver holds a heating target so that the heating target is insertable into and removable from the apparatus body. The heating device is disposed above the receiver, to heat the heating target. The partition partitions an upper space above the heating device into a first space facing the heating device and a second space facing an upper surface portion of the apparatus body.

Heating apparatus, image applier, and image applying method

A sheet stacker includes a sheet stack table on which a sheet is stacked and a sheet reversing section disposed above the sheet stack table. The sheet reversing section defines a sheet reverse passage to reverse a direction of conveyance of a sheet fed to the sheet reversing section. The sheet reversing section includes a first sheet guide to guide a bottom face of the sheet and a second sheet guide disposed downstream from the first sheet guide in a sheet conveyance direction in which the sheet is fed to the sheet reversing section. The second sheet guide to guide the bottom face of the sheet is attachable to and removable from an apparatus body.

Sheet stacker, image forming apparatus, and sheet conveyance control method

An image forming apparatus includes an image forming unit to form an image on a sheet, a sheet ejection section to which a relay unit and a sheet processing apparatus are removably coupled, a driving-side ejection roller disposed in the sheet ejection section, to eject the sheet outside the apparatus, a plurality of driven-side ejection rollers that are replaceable, one of which is disposed facing the driving-side ejection roller, and a roller holder removably secured to the sheet ejection section to hold the one of the plurality of driven-side ejection rollers. Each driven-side ejection roller has a shaft and a plurality of roller bodies attached to the shaft and lined in an axial direction of the shaft. The driven-side ejection roller is replaced with another driven-side ejection roller in accordance with whether or not the relay unit and the sheet processing apparatus are coupled to the sheet ejection section.

Image forming apparatus

An image forming apparatus includes an image forming unit, a conveyance unit, and an adhesive-surface guide unit. The adhesive-surface guide unit includes a second rotary body and an adhesive-surface guide member. The second rotary body is disposed at a position downstream from a first rotary body of a pair of rotary bodies of the conveyance unit in a conveyance direction. The adhesive-surface guide member is wound around the first and second rotary bodies to guide an adhesive surface of a print medium. The adhesive-surface guide unit is configured to press the adhesive-surface guide member against the adhesive surface, sandwich the print medium and the second rotary body between the pair of rotary bodies, move the print medium and the second rotary body together, and separate the adhesive-surface guide member from the adhesive surface at a side of the adhesive-surface guide unit at which the second rotary body is disposed.

An image forming apparatus including an image forming unit, a conveyor, and a string-shaped regulation member. The image forming unit forms an image on a recording medium. The conveyor is disposed opposing the image forming unit to convey the recording medium along a conveyance passage. The string-shaped regulation member is disposed between the image forming unit and the conveyance passage to regulate a distance between the recording medium and the image forming unit within a certain range.

An image forming apparatus includes a recording head, a liquid cartridge, a cartridge holder, a hook member, and an engagement portion. The recording head ejects liquid droplets. The liquid cartridge stores liquid to be supplied to the recording head. The cartridge holder replaceably mounts the liquid cartridge. The hook member is integrally formed with an inner wall face of the cartridge holder to engage the liquid cartridge when the liquid cartridge is mounted in the cartridge holder. The engagement portion is provided at an outer wall face of the liquid cartridge to engage the hook member.
