IMAGE FORMING DEVICE

PROBLEM TO BE SOLVED: To provide an image forming device that more strongly prompts users to replace a developing device of which the usage reaches a life.SOLUTION: The present invention relates to an image forming device. Then, the image forming device of the present invention includes: a developing device that comprises an electrostatic latent image carrier carrying an electrostatic latent image on the surface thereof, and supplies a developer agent to the electrostatic latent image formed on the surface of the electrostatic latent image carrier to develop a developer agent image; bias voltage application means that applies a bias voltage to a member adjacent to the electrostatic latent image carrier; life determination means that determines whether a usage of the developing device reaches a life; and a control unit that, when the life determination means determines that the usage of the developing device reaches the life, controls the bias voltage application means to cause the bias voltage to be applied to the member adjacent to the electrostatic latent image carrier during suspension of the developing device.SELECTED DRAWING: Figure 1 【課題】 使用量が寿命に到達した現像装置の交換をより強くユーザに促す画像形成装置を提供する。【解決手段】本発明は、画像形成装置に関する。そして、本発明の画像形成装置は、表面に静電潜像を担持する静電潜像担持体を備え、静電潜像担持体の表面に形成された静電潜像に現像剤を供給して現像剤像を現像する現像装置と、静電潜像担持体に隣接する部材にバイアス電圧を印加するバイアス電圧印加手段と、現像装置の使用量が寿命に到達したか否かを判断する寿命判断手段と、寿命判断手段が、現像装置の使用量が寿命に到達したことを判断した場合、現像装置の停止中に、バイアス電圧印加手段を制御して、静電潜像担持体に隣接する部材にバイアス電圧を印加させる制御部とを有することを特徴とする。【選択図】 図１
