Image forming device

Abstract

PURPOSE: To prevent the occurrence of distortion and deviation of an image by making the length from a transfer position to a pressing position, where the image is fixed with a fixing roll, shorter than a minimum usable transfer paper size and making the length from a write position, where the image is written on an image forming body, to said pressing position through the transfer position longer than a maximum usable transfer paper size. CONSTITUTION: The length from a transfer electrode 41 to a fixing roll 61 of a fixing device is set to dimensions L 1 shorter than a minimum usable transfer paper size, and the length from the write position where an image is formed on a photosensitive drum 11, namely, an exposure point P 1 to the fixing roll 61 through a developing device 31 and the transfer electrode 41 along the peripheral surface of the photosensitive drum 11 is set to dimensions L 2 obtained by adding an interval (x) between images in the peripheral direction to a maximum usable transfer paper size. When images are copied continuously on transfer papers of the same size by this image forming device, it is possible that the exposure action of the second image is started and terminated synchronously with the start and the end of the fixing action of the first image, and the variance of the speed of the photosensitive drum 11 accompanied with the fixing action during exposure is evaded.
