Image forming apparatus, developing apparatus, and finely-divided toner particle collecting apparatus

A developing apparatus for developing a latent image formed on an image carrier, using a developer including a toner and a carrier, the developing apparatus comprising:

• a developer conveying member that conveys the developer;
• a first collecting unit that collects, by generating a first electric field, the toner from the developer at a first position that is set halfway through a route of conveyance of the developer by the developer conveying member;
• and
• a second collecting unit that collects, by generating a second electric field, residual toner from the developer at a second position that is downstream of the first position in the route of conveyance of the developer.

• the image carrier is disposed to face the developer conveying member at a second position that is downstream of the first position in the route of conveyance of the developer, and
• at the second position, a second electric field is generated to move residual toner from the developer after the toner is collected therefrom by the first collecting unit, to the image carrier.
