    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： The image forming apparatus includes a photosensitive drum, an image forming unit, an intermediate transfer belt, a circuit of a drive motor which outputs information on a moving distance, a registration roller, a CPU which calculates the predetermined timing on the basis of the information on the moving distance output by the circuit of the drive motor at the time when a rotation speed of the intermediate transfer belt is switched from a first process speed to a second process speed, and a memory storing the information on the predetermined timing calculated by the CPU, wherein the CPU controls the registration roller so as to start the conveyance of the recording material at the predetermined timing stored in the memory. Consequently, a positional relation between a leading end of the recording material and a leading end of the image formed on the recording material can be set as a desired positional relation.
