Abstract
Official abstract text for this publication.
A cleaner includes a cleaning member electrostatically removing toner on an object; a first electricity supplier supplying a first voltage (or current) with polarity opposite to that of toner to the cleaning member; a toner collecting member collecting toner from the cleaning member; and a second electricity supplier supplying a second voltage with the polarity greater than the first voltage to the toner collecting member. The first and second electricity suppliers set plural setting values of the first and second voltages smaller than the targeted values of the first and second voltages, and first and second control members of the first and second electricity suppliers output first and second control signals while changing in step-by-step manner so that first and second output members of the first and second electricity suppliers apply the first and second voltage in step-by-step manner before the first and second voltages reach the targeted voltages.
First claim
Opening claim text (preview).
What is claimed is: 1. A cleaner comprising: at least one cleaning unit including: a cleaning member to electrostatically remove toner which is charged with a first polarity and which is located on a rotatable object to be cleaned; a first power supply to apply a first voltage or current with a second polarity opposite to the first polarity to the cleaning member so that the cleaning member electrostatically attracts the toner on the rotatable object; a toner collecting membe…
