摘要： A developer supply device is provided, which includes a transfer board including an activating section and an always-transferring section. The activating section is disposed in a position close to a developer holding member and lower than a position where development agent is transferred onto the developer holding member. The activating section is supplied with an activating voltage for making the development agent leave a developer transfer path and drop into the developer storage section during an activating process performed at an initial stage of a developer transferring operation while supplied with the transfer bias voltage after the activating process. The always-transferring section is disposed across a position facing the developer storage section to a position lower than and adjacent to the activating section, and always supplied with a transfer bias voltage during the developer transferring operation.

摘要： There is provided an image formation device, comprising a developer holding body having a developer holding surface; and a developer supply unit to supply the developer to a first position facing the developer holding surface by carrying the developer in a developer transport direction intersecting with the main scanning direction through use of effect of an electric field. The developer supply unit comprises a plurality of carrying electrodes each of which is formed to have a longer side extending along the main scanning direction. The carrying electrodes are arranged along the developer transport direction to carry the developer when a drive voltage is applied to the carrying electrodes. The developer supply unit has a developer carrying area formed such that, in the main scanning direction, the developer carrying area becomes narrower from an upstream side in the developer transport direction toward the first position along the developer transport direction.
