    • In an image forming apparatus, a recording head discharges liquid droplets onto a sheet conveyed on a conveying belt to form an image on the sheet. A sheet discharge device is provided downstream from the conveying belt in a sheet conveyance direction and is intermittently driven independently of and in synchronization with the conveying belt to convey the sheet in a sheet discharging direction. A voltage application device applies a voltage to a charger. A distance between the charger and a nip portion formed between a pressing member and the conveying belt for duplex printing is set so that a voltage applied by the voltage application device increases a charged potential of the conveying belt in an area electrostatically attracting a trailing end of a predetermined sheet and a leading end of a subsequent sheet.
    • 在图像形成装置中,记录头将液滴排放到在传送带上传送的片材上,以在片材上形成图像。 片材排出装置在片材输送方向上设置在输送带的下游,并且与输送带独立地且与其同步地间歇地驱动,以将片材沿片材排出方向输送。 电压施加装置向充电器施加电压。 设置充电器和形成在按压构件和用于双面打印的输送带之间的夹持部之间的距离,使得由施加电压装置施加的电压在静电吸引尾部的区域中增加输送带的带电电位 预定片材和后续片材的前端。
