摘要： An image forming apparatus includes a transfer roller that can be separated from an intermediate transfer belt. When an operational mode is switched from a multicolor mode to a mono-color mode, the image forming apparatus changes a rotational speed of the intermediate transfer belt to a level slower than a rotational speed of the intermediate transfer belt to be set in the multicolor mode to transfer a toner image to the intermediate transfer belt, then separates a first transfer member from the intermediate transfer belt, and after the first transfer member is separated from the intermediate transfer belt, the image forming apparatus increases the rotational speed of the intermediate transfer belt to a rotational speed to be set in the mono-color mode to transfer the toner image to the intermediate transfer belt.

摘要： There is provided an image forming apparatus including a rotation member used for image forming and a detector for detecting light from the rotation member. First waveform data of an image-formed surface used to form an image on the rotation member is acquired by the detector. Second waveform data of the image-formed surface used to form an image on the rotation member is acquired. The second waveform data includes at least part of a detected section of the first waveform data. Information on the actual circumference of the rotation member is calculated based on matching between the acquired first and second waveform data. The acquired first waveform data and second waveform data are compared to determine whether or not to use the calculated information on the circumference. When it is determined not to use the calculated information on the circumference, information on the circumference of the rotation member is recalculated.

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.
