Abstract:
1. An image forming device comprising: a developer carrying body having a developer supporting surface configured to support developer including a plurality of fine particles; and a developer supply device configured to supply the developer to the developer carrying body, while transferring the developer along a developer transfer path, wherein the developer supply device comprises: wherein the developer comprises a fine particle charged in a positive polarity and a fine particle charged in an negative polarity, and wherein the transfer voltage applying unit is configured to apply the traveling-wave shaped transfer voltages having waveforms, the waveforms making a fly height of the fine particle charged in the positive polarity higher than a fly height of the fine particle charged in the negative polarity, to the plurality of transfer electrodes, and the waveforms being respectively shaped such that a rising edge is steeper than a falling edge, to the plurality of transfer electrodes.
