摘要： The increasing ratio of development density to increase in potential difference between a photoreceptor and a development roller differs between the region where the potential difference is small and the region where the potential difference is large. The increasing ratio of development density at the region where the potential difference is small is smaller than the increasing ratio of development density at the region where the potential difference is large. Development is conducted under the developing characteristics in which the upper limit of the development density at the region where the increasing ratio of development density is small is at least 0.3.

摘要： A direct-feed type writing implement having two ends includes an ink tank and a pair of writing points, arranged at opposite ends of the ink tank. An ink collector is provided for each writing point. An air/liquid exchanger adjusts the internal pressure inside the ink tank by use of capillarity. An ink feeder is provided for each writing point. Each ink feeder includes a center core for feeding ink to the writing point. Air is inhibited from flowing into the ink tank through the ink collector air/liquid exchanger located at one end while the pen is being used for writing at the opposite end.

摘要： The present invention provides an ink follower for an aqueous ballpoint pen having an ink reservoir for directly preserving an ink, and this ink follower comprises at least a gel-like material having a predominantly viscous response and comprising a less volatile solvent having a viscosity of 5 Pa.multidot.sec or less and a hydrophobic thickening agent, and a solid piece having a specific gravity of 0.80 to 1.10. In addition, the present invention provides a ballpoint pen using this ink follower.The ink follower of the present invention is characterized by using the gel-like material having a high flowability and the solid piece for dispersing and absorbing impact. This ink follower has a strong drop impact resistance, in contrast to a conventional gel-like ink control plug. The aqueous ballpoint pen using this ink follower does not lose its function, even when it is dropped from a shelf at a height of 1.5 m.

摘要： A clicking-type ball point pen has a so-called double-clicking mechanism in which a clicking rod is projected by depression and is retracted by further depression. At least one undercut is formed in the inner surface of a rear barrel cylinder or a component fixed to the rear barrel cylinder to prevent a rotor and the clicking rod from being removed forward from the barrel cylinder. The barrel cylinder incorporates a writing element having a large diameter. A point assembly holder at the distal end of the barrel cylinder has a straight portion, which constantly urges a writing ball forward with a load of 1 g to 80 g, and an elastic portion having spring properties integrally, or in a contact state if the straight portion and the elastic portion are separate components. An ink present from the interior of the point assembly to a follower is defoamed such that a gas, e.g., air, water vapor, or a gas formed of a vaporized organic solvent, which is larger than 0.524 mm.sup.3 (a volume of a sphere having a diameter of 1.0 mm) is absent therein.

摘要： Press forming for preventing the ball from slipping out from the pen tip of a ball-point pen is carried out twice creating a sealing face brim having a width S and a curvature R substantially equal to that of the ball, inside the front part of the pen tip. Provided in the rear of the ball is a ball seat, and channels and longitudinal backlash which allow the ink to flow to the pen point are provided. Further, the front part of the point assembly may be formed with an open V-shaped tapered portion. A spring which constantly urges the ball forward may be provided inside the point assembly.

摘要： A ball-point pen of the present invention is provided which includes: a ball-point pen refill being accommodated in the barrel cylinder and having: a tip with a tip ball held at the front end thereof; an ink reservoir which stores low-viscosity oily ink and has an ink follower provided in the rear end of the ink; and a joint disposed between the tip and the ink reservoir. The joint further includes: a valve chamber holding a ball valve in its inside and communicating with the rear end of the tip; and a ball valve seat disposed on the rear side of the valve chamber for the ball valve in order to prevent backward flow of ink. With this configuration, it is possible to provide a ball-point pen which, without need of any cap, can create dense writing traces free from blotting and unevenness even when a low viscosity oily ink is used.
