An inkjet printer includes: at least one ink receptor having a tray shape with a bottom plate and an opening facing upward and being horizontally movable; and a suction unit. The at least one ink receptor is configured to receive ink ejected from at least one inkjet head as waste liquid. The suction unit includes at least one suction nozzle arranged above the bottom plate within a movable range of the at least one ink receptor and is configured to suction the ink in the at least one ink receptor through the opening with the at least one suction nozzle.

In a sealed letter producing device which folds and seals, with a content, an envelope sheet on which pressure-sensitive adhesives are provided, sealing with pressure rollers smaller than in conventional rollers is achieved. Pressure-sensitive adhesivesare provided in both edge portions in the width direction of an envelope sheet, and remoistening pasteis provided inwardly of both edge portions. The remoistening paste is moistened when the envelope sheet wrapping a content is bent and formed into an envelope, the entire surface of the envelope is pressurized by low-pressure rollers and adhered with the remoistening paste, and further only both edge portions of the envelopeare pressurized by an upper and lower set and a left and right pair of the pressure rollershaving a small width to adhere the pressure-sensitive adhesive. High pressure required for adhesion of the pressure-sensitive adhesives is only necessary in both edge portions of the envelope, and therefore small pressure rollerswill suffice.

A sheet reversing mechanism for an image forming apparatus including a switchback reverse path for reversing print sheets, including a transfer roller, a drive motor, and a driving force transmission mechanism. The transfer roller transfers a print sheet along the switchback reverse path. The drive motor rotates in a forward direction and in a reverse direction. The driving force transmission mechanism transmits driving force generated by rotation of the drive motor to the transfer roller. The driving force transmission mechanism includes a clutch configured to connect or disconnect transmission of the driving force to the transfer roller.
