請求の範囲第１項記載の電子写真式プリンタ。[Claims for Utility Model Registration] 1. A charging device that includes a corotron wire to which a high voltage is applied and a shield plate that shields the corotron wire portion, and that charges a photoreceptor and forms an electrostatic latent image when irradiated with light. In an electrophotographic printer, the electrophotographic printer comprises a developing device for developing the electrostatic latent image, a transfer device for transferring the developed toner image onto paper, and a fixing device for fixing the transferred image. An insulating sealing member made of an elastic material is provided between both ends of the photoreceptor in the longitudinal direction and both ends of the photoreceptor in the longitudinal direction, and is made of an elastic material to block floating objects such as dust that are attracted by the high voltage and enter the charger. An electrophotographic printer characterized in that it is arranged so as to surround the printer. 2. The electrophotographic printer according to claim 1, wherein the sealing member is made of a sponge-like non-breathable material having closed cells.
