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 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： In a free-ink type low-viscosity water-based ball point pen, the low viscosity water based ink 17 contains 40% or more of water as a main solvent and has a viscosity of 1.5 cps to 60 cps at a normal temperature. A collector 6 has a slender, slit-like ink groove 16 and an air vent groove 14. In a zone covering from a collector air-venting portion 15 to an outside air with which the collector air-venting portion 15 is communicated the collector 6 has a mouth piece 5 having provided therein the thin and elongate air vent groove 14. The maximum amount of ink stored in the collector 6 is made 15% or more of the capacity of an ink tank 9. The ink tank 9 is made detachable and has its main body formed of transparent or semi-transparent synthetic resin, the main body therefore enabling a residual amount of ink 17 to be visually recognizable from outside.

摘要： A ballpoint pen for use with ink having thixotropic (shear viscosity decreasing properties) and a joint for regulating the flow of the ink to the pen's tip through an entrance in the tip. The joint includes a valve chamber which is disposed in an approximately middle portion of the joint with respect to the axial direction thereof for holding a ball therein with play and has a ball seat in the rear part thereof, a cavity in front of the valve chamber and a conduit communicating with an ink reservoir. In this arrangement, in order to allow the ball to fit on the ball seat to prevent ink from flowing backward when the ballpoint pen is oriented upward and in order to ensure an ink flow when oriented downward, the joint portion is constructed such that an axis of path holding the ball valve with play, defined by the top surfaces of the ribs formed on the peripheral wall of the valve chamber, is made eccentric to the axis of the entrance and a channel is provided by the ribs on one side of the valve chamber space for the ink to flow therethrough.
