    • An electrostatic recording apparatus includes a developing agent carrier member provided to extend along a predetermined path. A developing agent convey unit conveys a developing agent along the surface of the developing agent carrier member. The developing agent carrier member has a step in a developing agent convey direction of its surface. A plurality of recording electrodes are aligned on an upper surface of the step of the developing agent carrier member and spaced apart from each other with gaps therebetween in a direction perpendicular to the developing agent convey direction, and project uniformly from the step. An opposite electrode is disposed to oppose the plurality of recording electrodes. A leaf spring member supports at least portions of the plurality of recording electrodes projecting from the step and can swing the projecting recording electrodes in directions to approach to and to separate from the opposite electrode. A voltage applying unit applies recording voltages to the plurality of recording electrodes in accordance with recording data to selectively transfer the developing agent conveyed along the surface of the developing agent carrier member to the opposite electrode.
    • 静电记录装置包括沿预定路径延伸的显影剂载体构件。 显影剂输送单元沿显影剂载体构件的表面输送显影剂。 显影剂载体构件具有其表面的显影剂输送方向的台阶。 多个记录电极在显影剂载体部件的台阶的上表面上对准,并且在垂直于显影剂输送方向的方向上彼此隔开间隔开,并从台阶均匀地突出。 相对电极设置成与多个记录电极相对。 板簧构件支撑从台阶突出的多个记录电极的至少一部分,并且可以在与相对电极接近并分离的方向上摆动投影记录电极。 电压施加单元根据记录数据向多个记录电极施加记录电压,以选择性地将沿着显影剂载体构件的表面传送的显影剂转移到对置电极。
