Classifier, developer, and image forming apparatus
摘要:
A classifier having a simple constitution for classifying powder with a high accuracy is provided. The classifier is provided with a transfer board having a plurality of electrodes for generating electric fields for transferring and hopping the powder by an electrostatic force. The classifier is further provided with an opposite roller generating an electric field for transporting and attaching the powder (toner) transferred and hopped on the transfer board to the opposite roller, which is opposite to the transfer board.
