Abstract
A separating apparatus for separating foreign matter from magnetic toner, includes a filter with openings allowing a toner to pass therethrough, a vibration generator for vibrating the filter in a substantially horizontal direction relative to a filter surface of the filter, and magnetic field generator for generating a magnetic field for attracting the magnetic toner through the filter.
Claims44
A separating apparatus for separating a foreign matter from magnetic toner, comprising:
- a filter having openings allowing a magnetic toner to pass therethrough;
- a vibration generating means for vibrating said filter in a substantially horizontal direction relative to a filter surface of said filter such that the magnetic toner moves in the substantially horizontal direction with the filter;
- and
- a magnetic field generating means for generating a magnetic field for attracting the magnetic toner through said filter in a direction in opposition to the pull of gravity when said filter is vibrating in the substantially horizontal direction.

An image forming apparatus for forming an image on a recording medium, comprising:
- (a) an image bearing member,
- (b) an image forming means for forming a toner image on said image bearing member;
- (c) a transfer means for transferring the toner image formed on said image bearing member by said image forming means onto the recording medium;
- (d) a cleaning means for removing a residual matter adhered to said image bearing member, after the toner image was transferred by said transfer means;
- (e) a separating means for separating the residual matter removed from said image bearing member by said cleaning means into foreign matter and magnetic toner, said separating means comprising a filter having openings for allowing a magnetic toner to pass therethrough, a vibration generating means for vibrating said filter in the substantially horizontal direction relative to a filter surface thereof such that the magnetic toner moves in the substantially horizontal direction with the filter, and a magnetic field generating means for generating a magnetic field for attracting the magnetic toner through said filter in a direction in opposition to the pull of gravity when said filter is vibrating in the substantially horizontal direction;
- and
- (f) a convey means for conveying the recording medium.
