    摘要： A photosensitive drum protecting device for use in a color electrophotographic printer is provided. The printer, in which developing device cartridges of various colors including photosensitive drums and developing rollers are installed, and a printing path contacting the photosensitive drums is formed, includes a photosensitive drum protecting device that simultaneously exposes or protects each of the photosensitive drums. All of the photosensitive drums disposed at front end portions of the developing device cartridges are covered by just one photosensitive drum protecting device. Thus, the complexity of the printer is reduced and the printer can be made more compact.

    摘要： Provided is a duplex printer and method of duplex printing. The duplex printer and method of printing includes a paper feeding belt that is vertically installed to form a first vertical surface; a photosensitive drum that is installed to contact the first vertical surface; and a transfer roller that is installed to contact an other surface of the first vertical surface contacting the photosensitive drum to transfer a toner image from the photosensitive drum onto a sheet of paper, which is supplied between the photosensitive drum and the paper feeding belt. A back surface feeding path of the paper is formed at an opposite side of the photosensitive drum in the paper feeding belt, and the paper is conveyed closely adhered to a surface of the paper feeding belt in the back surface feeding path of the paper. Accordingly, since the paper feeding belt is used as the back surface feeding path of the paper, the number of additional devices such as guide plates and convey rollers can be reduced, and a compact color printer can be fabricated.

    摘要翻译： 提供了一种双面打印机和双面打印方法。 双面打印机和打印方法包括垂直安装以形成第一垂直表面的送纸带; 安装成与第一垂直表面接触的感光鼓; 以及转印辊，其被安装成接触与感光鼓接触的第一垂直表面的另一表面，以将调色剂图像从感光鼓转印到供应在感光鼓和供纸带之间的一张纸上。 纸张的后表面馈送路径形成在供纸带的感光鼓的相反侧，并且纸张被紧密地传送到纸张的背面馈送路径中的送纸带的表面。 因此，由于采用进纸带作为纸张的背面进给路径，所以可以减少诸如导向板和传送辊等附加装置的数量，并且可以制造小型彩色打印机。

    摘要： A color image forming device has an image forming cartridge including a cartridge frame that receives a plurality of image forming units. A movable fixing part supports at least one of the shafts of a plurality of photosensitive bodies disposed in the image forming units so that the shaft is rotatably fixed. The shafts of the other photosensitive bodies are movable and rotatable when the plurality of image forming units are received in the cartridge frame. A mounting frame receives the image forming cartridge, and has a shaft receiving part formed at a position corresponding to the ends of the shafts of the photosensitive bodies. The color image forming device accurately fixes the position of the shafts of the photosensitive bodies when the image forming cartridge is assembled in the mounting frame, thereby producing a high quality image reliably.
