Abstract
A developing device includes: a first developing body that develops a developing agent image on a development surface using a developing agent; a second developing body that develops a developing agent image on the development surface using the developing agent; and a sealing member that is disposed between a region where a first delivery pole and a second delivery pole are opposed to each other and the development surface, and adjacently to the first developing body and the second developing body at distances so small that developing agents formed as magnetic brushes on a first conveyance pole and a second conveyance pole respectively can touch the sealing member to secure sealing to prevent the developing agent from leaking to the outside of a device body.
