Abstract
A method () and apparatus () that detects carrier particles () in an electrophotographic device is disclosed. The apparatus may include an image carrying member (). The image carrying member may have a first side () and have a second side () opposite from the first side. The image carrying member may be configured to operate in a direction of motion (). The image carrying member may also be configured to transport an image on the first side. The apparatus may also include a magnet () coupled to the second side of the image carrying member. The magnet may have a length (). The length of the magnet may be at an angle () of greater than zero and less than 90 degrees to the direction of motion of the image carrying member. The magnet may be configured to attract toner carrier particles transported on the image carrying member. The apparatus may also include a first sensor () coupled in proximity to the first side of the image carrying member and coupled in proximity to the magnet. The first sensor may be configured to sense the toner carrier particles attracted by the magnet. The first sensor may also be configured to output a first signal corresponding to the sensed toner carrier particles.
