摘要： A density controlling method for controlling the density of toner applied to the surface of a photosensitive drum of a photocopying machine is disclosed herein. A small area of the drum is irridated with light, and toner is applied thereon. A photo-transistor sensor senses the density of the toner, and a signal produced by the sensor is compared to a reference signal indicative of optimal toner density. The difference signal is then applied through a CPU to control both the bias voltage of the developing system and the speed of the toner motor.

摘要： A magnetic recording medium is constructed with a substrate made of glass, one or two underlayers, and a magnetic film. In order that the easy magnetization axis of the magnetic film is parallel to the magnetic film, an underlayer having an NaCl crystallographic structure is superposed on the substrate. A magnetic film made of a Co based alloy having a hexagonal close packed crystallographic structure is formed on this underlayer, putting an underlayer made of a material having a body centered cubic crystallographic structure therebetween at need. Magnetic anisotropy of the magnetic film is increased by forming grooves in a predetermined direction in a surface portion of the substrate. These grooves play a role also for defining the orientation of the underlayer made of the material having an NaCl crystallographic structure.
