Abstract
Provided is a cleaning device including a brush roll that removes residual toner remaining on a surface of a toner image carrier provided in an electrophotographic apparatus, and a pressure detector that contacts the surface of the brush roll with preload, and outputs a detected pressure value to a determination unit that is provided in the electrophotographic apparatus to determine the adhesion state of toner to the brush roll.
Claims4
A cleaning device comprising:
- a brush roll that removes residual toner remaining on a surface of a toner image carrier provided in an electrophotographic apparatus;
- and
- a pressure detector that has a pressure-sensitive surface, the pressure-sensitive surface directly contacting a surface of the brush roll with preload, and outputs a detected pressure value to a determination unit that is provided in the electrophotographic apparatus to determine an adhesion state of toner to the brush roll;
- wherein the pressure detector is a pressure sensor device, and
- the pressure sensor device is provided in a state where an end portion thereof has entered bristle tips of the brush roll during a normal state of operation.
