Abstract

1281485 Electro-photographic copiers INTERNATIONAL BUSINESS MACHINES CORP 28 April 1970 [19 May 1969] 20215/70 Heading G2H After transfer of a developed image from a photo-conductive drum, residual developer is cleared therefrom by a brush 41, Fig. 1, or an air knife 101, Fig. 4; a lamp being provided at the cleaning station to illuminate the drum and disperse residual charge therefrom while the drum is being cleared. In Fig. 1, lamp 55 is mounted inside rotating brush 41, a vacuum cleaner 45, 47 drawing off developer particles. The construction of the brush and materials therefor are described in detail. In Fig. 4, a lamp 103 and air knife 101 are employed, developer particles being drawn off by suction through a housing 105.
