Abstract:
1. A developing device for storing a developer containing a ferromagnetic substance and supplying the developer to an image bearing member to develop an electrostatic latent image formed on the image bearing member, comprising: a developer tank which stores therein the developer; a partition wall which divides an internal space of the developer tank into: an upper developer conveying section which is located in the upper conveying path and conveys the developer in the developer tank in the substantially horizontal direction, the upper developer conveying section conveying the developer toward the other end side of the partition wall in the longitudinal direction thereof from the one end side of the partition wall in the longitudinal direction thereof; a lower developer conveying section which is located in the lower conveying path and conveys the developer in the developer tank in the substantially horizontal direction, the lower developer conveying section conveying the developer toward the one end side of the partition wall in the longitudinal direction thereof from the other end side of the partition wall in the longitudinal direction thereof; a developer pumping conveying section which is located in the pumping conveying path and conveys the developer in the developer tank upward in a substantially vertical direction, the developer pumping conveying section comprising: an attracting magnet located in a position spaced from the rotational tube in the horizontal direction, the attracting magnet attracting the developer in the developer tank at least in the horizontal direction.
