    摘要： The image forming device of the present invention relates to an image forming device having a moving member which moves while pressing a recording material against an image carrying member as the means of transferring the image on the image carrying member to the recording material. Further, the image forming device has a pair of moving members for fixing the image by conveying the recording material sandwiched therebetween, of which the moving member on the side not in contact with the unfixed image is a moving member having an elastic material layer and a resin surface layer. Further, the present invention has the surface of the moving member of the fixing member on the side not in contact with the unfixed image which is better mold releasability with that of the moving member of the image forming device.

    摘要： In a laser beam printer, automatic optical quantity (APC) control is performed based on an optical quantity detection output to generate a laser beam having a predetermined quantity of light. In each scanning cycle, APC is effected by utilizing a period (unblanking period) in which the laser device is forcibly actuated to generate a horizontal synchronization signal. The unblanking period may be changed according to the print paper size or image formation/non-image-formation periods. Also, light quantity control may be effected through a plurality of scanning cycles before image formation and may be effected by utilizing the unblanking period during the period corresponding to the intervals of print sheets. Techniques also provided to prevent a transfer unit from being contaminated by toner images formed as a byproduct of APC.

    摘要： An image forming apparatus has an image forming unit which is detachably mounted in the stationary main part of the apparatus. The unit includes an image carrier with a photosensitive layer, a charging device capable of electrostatically charging the image carrier in contact therewith, and a housing supporting the image carrier and the charging device and provided with an exposure opening. An air flow is positively formed such that, with the image forming unit mounted in a predetermined mounting portion in the apparatus, air flows from regions near both ends of the image carrier towards the exposure opening past a region where the charging device contacts the image carrier. With this arrangement, ozone generated in the image forming unit due to operation of the contact type charging device is efficiently carried away from the image forming unit, thus eliminating generation of image defects attributable to presence of ozone and other discharge products.
