摘要： An image forming apparatus includes a detector for measuring the surface potential of a photosensitive member on which an electrostatic latent image is formed and a controller which regulates image formation plural times in accordance with the measured surface potential based on the length of time between image formations. In another aspect, the image forming apparatus includes a light source and a setting device for manually setting the quantity of light therefrom between a maximum and minimum value. A test sample of a predetermined optical density is arranged to be illuminated by the light source so as to produce a test light for projection onto a recording medium. A detector detects an electrical surface condition of the test-lighted recording medium. In response to the detected electrical surface conditions, and a controller regulates the image formation in accordance with the detector. The light from the light source is adjusted so that illumination of the test sample assumes a standard value intermediate the maximum and minimum values, and so that illumination of an original assumes the value set by the setting device.

摘要： An image-forming machine includes a detachably mountable process unit. The process unit has a rotatable drum having an electrostatographic material thereon, a corona discharger, a developing device and a cleaning device. The developing device includes a development housing for holding a developer, a developer applicator for applying the developer to the electrostatographic material, and an agitating device for stirring the developer in the development housing. An agitating member of the agitating device is arranged to prevent damage of the agitating device due to forces resisting agitation motion by the agitating member. The developer applicator has a sleeve member for holding a developer on its surface, and a developer regulating blade which regulates the developer layer thickness, on the surface of the sleeve member, to provide an uniform developer thickness in the width direction. The cleaning device includes a toner removing device for removing residual toner from the electrostatographic material, a toner collecting chamber and a toner conveying passage extending from the toner recovery housing to the toner collecting chamber. The toner removing device includes a cleaning blade which, when the process unit is mounted at a predetermined position in the image-forming machine, is moved from a non-operative position away from the electrostatographic material to an operative position wherein it is brought elastically into contact with the electrostatographic material. A toner conveying device having a coil is disposed in the toner conveying passage.

摘要： Disclosed is a method for causing bubbles in a fluid to coalesce into a coherent mass by use of a vessel having a cylindrical space therein wherein the fluid is caused to flow into the vessel at such a velocity that a vortex is generated to flow from one end of the space to the other while establishing a state in which the pressure on the center axis of the cylinder rises from one end toward the other, then reaches a maximal value and thereafter drops, and this coalescing of the bubbles is effected at the field near the axis of the vortex and between a position close to the inflow position and the position of the highest pressure. The method greatly facilitates deaeration.

摘要： The ratio of the length of the light path between an original to be copied and a lens to the length of the light path between the lens and a photosensitive medium is changed by the copying magnification changing operation. That is, for example, the lens is brought nearer to the photosensitive medium. After this magnification changing operation, a reference light is thrown upon the photosensitive medium through the lens. The potential of the area of the photosensitive medium illuminated by the reference light is detected, and the output of photosensitive medium charging means is controlled correspondingly to that potential.
