Patent number: 5382490Abstract: An electrophotographic toner containing a specific compound as the charge control agent is described. The electrophotographic toner according to the present invention have a sharper distribution of charge and better moisture resistance and charge durability than those of a toner wherein a conventional charge control agent is used. Therefore it can provide an image having a very high gradation and has a very high capability of repeatedly forming an image. Since the charge control agent, as such, is essentially colorless, a colorant can freely be selected according to a hue required of a color toner and the toner is not detrimental to the hue inherent in a dye and a pigment. The charge control agent is highly safe to environment.Type: GrantFiled: August 18, 1992Date of Patent: January 17, 1995Assignee: Nippon Kayaku Kabushiki KaishaInventors: Shigeo Yamamura, Junko Yamamoto, Tadayuki Kiyoyanagi, Masaharu Nomura

Patent number: 5225305Abstract: An electrophotographic toner containing a specific compound as the charge control agent is described. The electrophotographic toner according to the present invention have a sharper distribution of the amount of electrification and better moisture resistance and time stability than those of a toner wherein a conventional charge control agent is used. Therefore it can provide an image having a very high gradation and has a very high capability of repeatedly forming an image. Since the charge control agent, as such, is essentially colorless, a colorant can freely be selected according to a hue required of a color toner and the toner is not detrimental to the hue inherent in a dye and a pigment.Type: GrantFiled: August 27, 1991Date of Patent: July 6, 1993Assignee: Nippon Kayaku Kabushiki KaishaInventors: Tadayuki Kiyoyanagi, Junko Yamamoto, Shigeo Yamamura
