Title: Magnetic toner
Inventor: KATO SEIICHI
IPC: G03G9/083
Filed: 1985-05-31
Abstract: PURPOSE:To prevent the decrease of an image density by repeated uses by incorporating a magnetic material treated with a compd. having >=2 isocyanate groups into a title toner. CONSTITUTION:The magnetic material treated with the compd. having >=2 isocyanate groups (-NCO) is used and the acid value of a binder resin is made 10-100. The compd. having >=2 isocyanate groups makes the magnetic material hydrophobic by reacting with the OH group on the surface of the magnetic material, thereby improving the dispersibility of the magnetic material in the binder resin. The magnetic material adheres securely with the binder resin by reacting with the COOH group or OH group in the binder resin. The compd. having >=2 isocyanate groups is dissolved in 10-100 times volume of an org. solvent and after the soln. is stirred thoroughly for 1-2hr with the magnetic material, the soln. is filtered and is dried for 24-48hr in a thermostatic chamber kept at 40-80 deg.C. The compd. having >=2 isocyanate groups includes tolylenediisocyanate, etc. The toner which obviates the decrease of the image density even in repeated development is thus obtd.

Abstract: PURPOSE:To enable a cylindrical body to vibrate due to supersonic wave so that printing density may be secured even if printing pressure is at low level by connecting a high-frequency power supply to an electrode of a cylindrical body consisting of complex piezoelectric elements provided on the external periphery of a platen and keeping the high-frequency power supply ON while a printing wire is in contact with a printing medium on the surface of the cylindrical body. CONSTITUTION:A platen 1 is a thin-wall hollow cylinder made of aluminum alloy and made freely rotatable with a cylindrical body 2 consisting of complex piezoelectric elements fixed to the external periphery of the platen through an insulation layer 3. That is, the cylindrical body 2 has piezoelectric ceramic elements 21 of for instance, Pb (Zr, Ti) O3 connected through a resin layer 25. In addition, electrode layers 22, 23 are provided on the internal and external surfaces of the platen respectively, and a protective layer 24 of hard rubber is provided on the external surface of the electrode layer. When a voltage is applied to the electrode layers 22, 23 from, e.g. a 100kHz high-frequency power supply, the piezoelectric ceramic elements 21 vibrate under the effect of supersonic wave in a diametral direction of the cylindrical body 2 transmitting the vibration even to recording paper on the platen 1. If printing wire in a printing head is selectively driven by means of electric signal and the recording paper is pressed via ink ribbon, the recording paper vibrates due to supersonic wave, even through the pressure is at low level. Thus printing density can be kept at the same or higher level as or than that of the conventinoal printer.
