摘要： An image forming apparatus includes a plurality of image bearing members (12) bearing latent images, image forming units (13) for forming the latent images on the image bearing members, developing units (11) for developing the latent images on the image bearing members, a transport belt (18) for transporting a transfer member on which images of different colors developed by the developing units are successively transferred as the transfer member is transported, and image pickup elements (19), arranged obliquely to a main scan direction of the image forming units and located on a downstream of a most downstream one of the image bearing members along a direction in which the transport belt transports the transfer member. The image pickup elements detect as image information transmitted or reflected light quantity distributions of regions which include marks transferred on the transport belt from the image bearing members. The image forming apparatus further includes a correction unit (42) for detecting correction quantities from error quantities of marks transferred from the image bearing members other than a reference image bearing member with respect to a reference mark transferred from the reference image bearing member based on the image information detected by the image pickup elements, and correcting positions of the latent images formed on the image bearing members other than the reference image bearing member depending on the correction quantities.

摘要： A spindle unit control method controls a plurality of spindle units which rotate in synchronism with each other, and comprises with respect to each of the spindle units a first step of obtaining a phase error by comparing phases of a detection signal indicating a rotary reference position of the spindle unit and a first clock signal, a second step of generating a second clock signal having a phase which is adjusted by delaying or advancing the phase of the first clock signal by the phase error, and a third step of controlling the rotation of the spindle unit by a phase locked loop based on the detection signal and the second clock signal. The first clock signal is used in common with respect to each of the spindle units, and the second clock signal is independent for each of the spindle units.
