Title: Electrophotographic toner
Inventor: KUBO TSUTOMU
IPC: G03G9/097
Filed: 1990-09-18
Abstract: PURPOSE:To obtain the toner having good electrostatic chargeability and flowability by adding an external additive having the polar group different from the polar group of the polarity control agent on the surface of the toner to the toner. CONSTITUTION:The external additive having the polar group different from the polar group of the polarity control agent on the surface of the toner is added to the toner. For example, the toner surface eventually has an amino group if a nigrosine dye generally used as the polarity control agent is used and, therefore, a metal oxide treated with an alkyl coupling agent, a metal oxide treated with a quaternary ammonium coupling agent, etc., are used as the surface treating agent of the external additive. The amt. of the external additive to be used is determined by the electrostatic chargeability, staining of a photosensitive body, etc. The toner having the stable electrostatic chargeability and flowability in spite of an environmental change and after long-term resting is obtd. in this way.

IPC: G11B5/84
Filed: 1989-09-26
Abstract: PURPOSE:To reduce the scratching on a magnetic recording medium by a head in a video tape recorder and to reduce the fluctuations of output and the filled-up head-gap by applying treatment for increasing the binding force with a lubricant after a protective layer is formed. CONSTITUTION:The protective layer 4 is formed on a magnetic recording medium by plasma CVD, etc., and an oxide layer 5 is formed on the protective layer 4 in vaccum. The deposit generated when the protective layer 4 is formed and the contaminant absorbed when the medium is attached to or detached from the plasma CVD device are liberated and removed in the initial surface cleaning when the oxide layer 5 is formed or liberated as a gas by the heating using a heat source. Furthermore, since the oxide layer 5 immediately reaches the vapor deposition device for forming the lubricant layer 6 with the surface activated, the protective layer 4 is easily chemically combined with the lubricant layer 6 through the oxide layer 5, and the tough lubricant layer 6 is formed. Consequently, the scratching of the medium by the head is reduced in the recording and reproduction of a video tape recorder, and the fluctuations of output and blinding of the filled-up head-gap are prevented.
