摘要： There is provided an image forming apparatus which shortens the time taken for circumference detection and measures the circumference at high precision without obstructing downsizing of the apparatus. To accomplish this, the image forming apparatus detects, at an arbitrary timing, the physical pattern of the image-formed surface of a rotation member that changes over time. In the second round, the image forming apparatus detects the second pattern at a timing a predetermined time after the arbitrary timing. By using the detected patterns, the image forming apparatus obtains information associated with the circumference of the rotation member.

摘要： The speed at which transfer-material enters a transfer region is controlled to prevent a phenomenon in which a toner image on an intermediate transfer belt is scraped by the leading edge of the transfer-material when the toner image is transferred onto the transfer-material. While the conveying speed of the transfer-material in a transfer nip coincides with the speed of the intermediate transfer belt, the transfer-material is conveyed at a speed lower than the peripheral speed of the intermediate transfer belt when the leading edge of the transfer-material comes into contact with the intermediate transfer belt, and the conveying speed of the transfer-material is increased by the time when the transfer-material enters the transfer nip.

摘要： An image forming apparatus has an image bearing member, and a density detecting device for detecting the density of an image for density detection formed on the image bearing member. Image forming conditions are controlled on the basis of an output from the density detecting device. The density detecting device has a regular reflection type density detecting device for detecting the density by regular reflection light from a portion to be detected, and a diffuse reflection type density detecting device for detecting the density by diffuse reflection light from the portion to be detected. The output value from the diffuse reflection type density detecting device is corrected on the basis of the output value from the regular reflection type density detecting device which has detected a reference image, and the output value from the diffuse reflection type density detecting device which has detected the reference image.

摘要： There is provided an image forming apparatus that accurately obtains the dynamic characteristic of the apparatus when a foreign substance is adhered to a driving roller for driving an endless belt, such as a facing roller. To accomplish this, the image forming apparatus uses an optical sensor to detect information of a foreign substance on the facing roller. When it is determined that there is no foreign substance information, the image forming apparatus executes profile detection of an intermediate transfer belt using the nominal circumference of the facing roller. When the optical sensor detects foreign substance information, the image forming apparatus measures the circumference of the facing roller, and performs profile detection of the intermediate transfer belt using the measured circumference of the facing roller.

摘要： The type of printing medium on which an image will be formed is discriminated based upon the image of the medium surface read by an image reading unit for reading the surface as an image. If the discriminated medium type is other than a prescribed printing medium, the image is formed without changing an image formation parameter. When the type of printing medium and the state of the surface are discriminated, image formation can be performed in the most stable image forming mode if an abnormality occurs.
