Abstract

1442532 Developing electrostatic images MINOLTA CAMERA KK 18 Jan 1974 [25 Jan 1973] 02452/74 Heading G2H Magnetic brush developing roller 1 is both fed with powder developer and stripped of excess developer by vaned developer-mixing agitator 14, which is located above the roller 1 and is so constructed and rotated that the buckets between its vanes, transport and mix the developer. Fresh toner is added by dispenser 11. Two developing rollers may be used with one agitator, which may be located above one roller or above both.
