摘要： Toner images of different colors are superimposed on a transfer belt of an endless type from image carriers, to form a full color toner image. A tension roller maintains a tension of the transfer belt. A driving roller drives the transfer belt. A biasing unit applies the tension to the tension roller. A holding unit holds the tension roller. An image reading sensor detects the toner image formed on the transfer belt. The image reading sensor is disposed in the holding unit, in an opposite position to the tension roller with respect to the transfer belt.

摘要： A transfer device that transfers color visual images of different colors from image carriers to each of first and second sides of a recording medium. The transfer device includes a transfer element that holds and moves the recording medium, transfer bias applying devices that apply transfer biases to the recording medium by the transfer element to transfer the color visual images from the image carriers to the recording medium, respectively, and an adsorbing bias applying device that applies an adsorbing bias to the recording medium to adsorb the recording medium to the transfer element. A polarity of the adsorbing bias applied to the second side of the recording medium is opposite to that of electric charge given to the recording medium due to electric discharge generated when the recording medium is separated from the image carriers after passing through transfer nip parts formed between the image carriers and the transfer bias applying devices.

摘要： A method for evaluating an electric resistance member of an image forming apparatus which can maintain good image quality, without the occurrence of transfer defects such as insufficient transfer, even in a long-term use. An intermediate transfer belt of the image forming apparatus, which is evaluated based on a fluctuation characteristic of the resistivity in a period of continuous voltage application, is used. The absolute value Δρs of the amount of changes in the surface resistivity of the intermediate transfer belt within 2 seconds to 100 seconds from the beginning of voltage application is 0.3 [Log(Ω/)] or less, when the surface resistivity ρs is measured by applying a voltage of 500 V. The absolute value Δρv of the amount of changes in the volume resistivity within 2 seconds to 100 seconds from the beginning of voltage application is 0.5 [Log(Ω·cm)] or less, when the volume resistivity ρv is measured by applying a voltage of 200 V.

摘要： An image forming apparatus includes a belt member to convey a sheet-formed medium, a belt supporting device to support the belt member, and a plurality of recording units including rotating image bearing members arranged in a conveying direction of the sheet-formed medium by the belt. The image forming apparatus performs processes of (1) forming a latent image on a surface of each image bearing member, (2) developing each latent image into a toner image with toner, and (3) then transferring each toner image onto the sheet-formed medium carried on the belt. A detection device detects arbitrary toner image patterns formed at the plurality of recording units and then directly transferred onto the belt, for obtaining information about density and placements of images without the toner patterns being deteriorated by contacting following downstream recording units.
