摘要： A writing instrument cap having a clip as a separate part. The clip attachment, to which the clip is fitted, is projectively formed on the outer periphery of the cap. The clip attachment is formed with a vent hole penetrating between the interior and exterior of the cap and raised portions for attachment of the clip. The raised portions are provided on both sides of the vent hole, with respect to the circumference of the cap. When the clip is attached to the clip attachment, the clip covers the clip attachment and the vent hole and creates a clearance between the clip interior and the clip attachment so as to establish an air passage that communicates between the vent hole and the outside atmosphere.

摘要： In a writing instrument with a collector of the present invention, an ink absorber made up of a fabric sliver etc., capable of keeping ink therein is disposed inside the ink tank and is connected to the center core, longitudinal groove or the like as an ink feeder portion. The ink absorber is adapted to have a length at least reaching to a position more rearwards than the approximate center of the ink tank and has an outside diameter that is sized to be smaller than the inside diameter of the ink tank so as to create a space around itself for permitting free-state ink to move freely while the collector has a lead portion for establishing connection enabling ink to be led from the ink absorber to the air/liquid exchanger. Specifically, the lead portion of the collector may be configured of a projecting portion directly inserted into and connected with the ink absorber and a lead channel formed on the projecting portion. Alternatively, the lead portion may be formed, instead of being directly inserted to or connected with the ink absorber, by providing an ink lead channel capable of leading ink, which is connected to the center core, longitudinal groove or the like as an ink feeder portion that is connected to the ink absorber.

摘要： In a free-ink type collector writing instrument, the collector is formed with a partitioning portion for substantially shutting off the ink tank from the outside air, auxiliary retaining grooves are formed on the ink tank side with respect to the air/liquid exchanger of the partitioning portion while main retaining grooves are formed on the front side with respect to the air/liquid exchanger of the partitioning portion, a wide groove formed across the auxiliary retaining grooves for connecting the air/liquid exchanger and the ink tank is formed with a narrow groove extending from the air/liquid exchanger side to the ink tank side and lateral grooves capable of leading ink into the auxiliary retaining grooves. It is further effective if the capacity ‘ie’ of the auxiliary retaining grooves and the capacity ‘is’ of the main retaining grooves are designed so as to satisfy a relation ‘is>ie>0.05·is’ or if effective partitioning portion grooves are formed.

摘要： A developing device includes a developer carrier having a surface carrying a one-component developer thereon, developer control member abutting against the developer carrier to control a thickness of a layer of the developer, and a charge generation device provided downstream of the developer control member, as seen in a direction of a rotation of the developer carrier, and applying electric charge of a single polarity to a developer layer on the developer carrier, wherein the developer is charged under a condition that internal to the developer layer there occurs small aerial discharge caused by an electric field created by electric charge applied to a surface of the developer layer. Thus, the developing device can use a one-component developer, does not require toner having its components subtly adjusted and can cancel toner charged opposite in polarity, to form an image of high quality.
