摘要： The present invention is intended to save warm-up time of a toner image fixing device for fixing a toner image by heating and reduce manufacturing cost of the device. Elastically-deformable heat-resistant belt (31) is made in form of a cylinder of nickel which accommodates therein a heater lamp (32) and a reflecting plate (33) for concentrically transferring radiant heat from the heater lamp (32) onto a contacting portion of the cylinder-like belt with a recording paper (28) carrying a toner image (38). When the recording paper (28) is transported along a guiding plate (50), the driving roller (54) rotates the heat-resistant belt (31) in contact with the recording paper (28). At this time, the rotating belt (31) and the guide plate (50) are pressed against each other, thereby the belt (31) is elastically deformed in radial direction. The recording paper (28) is transported being pressed by the belt (31) and, thereby, the toner image (38) is fixed onto the recording paper (28) by heat.

摘要： An electrophotographic printing machine is provided with a photoreceptor (1) whereon a transparent electrically conductive layer (1b) and a photoconductive layer (1C) are successively formed. A visible image is formed on the photoconductive layer (1c) by exposing the photoconductive layer while applying a voltage across toner (T) supplied onto the surface of the photoreceptor (1) and the transparent electrically conductive layer (1c). The exposing energy of the exposure unit is set so as to satisfy an equation: VL >/= VD - VD1, where VD1 designates the surface electric potential of the photoreceptor (1) that is exerted when the surface of the photoreceptor (1), originally having a surface electric potential of virtually zero V, passes by the area in contact with the toner; VD designates the saturation value of the surface electric potential of the photoreceptor (1) that is attained after the surface of the photoreceptor (1) has successively passed by the area in contact with the toner; and VL designates a lowered surface electric potential of the photoreceptor that is to be reached by an exposure. Therefore, good picture images without being affected by residual images can be obtained.

摘要： In an image-forming apparatus of the present invention, below a document reading section (100), an image-forming section (200) is placed, and a first paper-discharge section (234) for discharging a sheet of paper bearing an image formed in the image-forming section (200) is installed. Between the document reading section (234) and the first paper-discharge section, a post-treatment device (300), which carries out post-treatments such as an adjusting process and a stapling process for sheets of paper subjected to the image-forming process is a virtually horizontal state, is installed. In such an image-forming apparatus having the discharging means on the installation plane of the apparatus, it is possible to provide an image-forming apparatus which can effectively utilize the discharging means, even in the case when the post-treatment device is attached, and can also minimize the installation area of the entire apparatus.
