    摘要： An image forming apparatus is provided with a latent image forming member for forming first and second electrostatic latent images on an image bearing member. A first developer forms a first visualized image by developing the first electrostatic latent image, and a second developer provides a second visualized image by developing the second electrostatic latent image. The second developer acts on the image bearing member after the first visualized image is formed on the image bearing member, and the second developer includes a developer carrier for carrying a developer to a developing position where the developer is supplied to the image bearing member. A vibratory voltage is applied to the developer carrier of the second developer. A controller changes a duty ratio of the vibratory voltage. The vibratory voltage has a first peak for forming an electric field to urge the developer away from the developing carrier toward the image bearing member and a second peak for forming an electric field to urge the developer away from the image bearing member toward the developer carrier. The first peak and second peak are alternately applied, and the controller changes a duty ratio while maintaining the second peak substantially constant. Furthermore, the controller changes the duty ratio by changing the first peak.

    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： 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.

    摘要： An image forming apparatus has an image supporting member for supporting a toner image, a transfer rotating member forming a nip with the image supporting member and electrostatically transferring the toner image formed on the image supporting member to a recording material, a fixing device for fixing the toner image to the recording material holding the toner image, and a guide member for guiding the recording material so that the angle between the direction of separation of the recording material from the transfer rotating member and the tangent to the image supporting member at the center of the nip is at least 2.degree. in a direction toward the image supporting member. The fixing device has a fixing rotating member, which contacts the toner image on the recording material and to which a bias of the same polarity as that of the toner is applied, and a pressure rotating member in pressure contact with the fixing rotating member so as to hold the recording material between the fixing rotating member and the pressure rotating member.
