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.

摘要： A developing apparatus includes a developer carrier carrying a developer on its surface, a developer regulating member regulating layer thickness of the developer, a charge amount control member controlling the charge amount of the developer and a charge supplying apparatus downstream of the charge amount control member. The charge amount control member controls the amount of charges of the developer, by causing the developer fly over the developer carrier, using an AC voltage applied between the developer carrier and the charge amount control member, and by applying the electric charges generated by gas electrolytic dissociation caused by the AC voltage. By this structure, a developing apparatus can be provided which can improve stability of development and image quality, without necessitating delicate arrangement of the component materials of the developer.

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： 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.
