field between removal surface 33 and sleeve 15 that urges the carrier to removal surface 33 further rotation of removal roller 29 brings whatever carrier has been attracted to surface 33 to a skive blade 37 which cleans surface 33 allowing carrier to fall into a removable holding container 39 where the serviceman can periodically remove the particles in operation during toning v bias toning applied by variable is power source 19 might be set at 100 v for charged area development using positive toner with a negative electrostatic image v bias removal might be set by variable power source 35 at an appropriate level to inhibit attraction of either carrier or toner to it for example at 100 v or ground to remove carrier v bias toning is set at ground while v bias removal is set at 600 v to cause the negatively charged carrier to be attracted to the removal device in doing discharged area toning with a negatively charged image and negatively charged toner toning is accomplished with both the v bias toning and the v bias removal at 500 v dc carrier removal is accomplished then by having v bias removal at 600 v and v bias toning at ground in each instance the change in biases is done for a short period of time say five seconds during running of the apparatus periodically say every 100 copies to remove a small amount of carrier into the holding container 39 which carrier is replaced along with the addition of.
