摘要： A sheet feeder of a friction pad separation type, which can be included in an image forming apparatus, includes a feeder body, a rotary feed body, a separation body, a holder, and a leaf spring. The rotary feed body is disposed in the feeder body and feeds a recording medium along a sheet conveying direction. The separation body is fixed to the feeder body while facing the rotary feed body. The separation body separates the recording medium with the rotary feed body. The holder has a rotary shaft and holds the separation body while being rotatably supported by the rotary shaft. The leaf spring has a flexible deforming part that contacts an area adjacent to the rotary shaft and a line of action of a pressing force of the flexible deforming part passing close by the rotary shaft.

摘要： An image forming apparatus includes an image bearer, an image forming unit, an intermediate transfer member, a secondary transfer member, an image detector, a computing device, and a conveyor device. The computing device calculates a traveling speed of the intermediate transfer member based on detection information provided by the image detector. The conveyor device continuously transports to a secondary transfer portion a plurality of recording media one by one at a predetermined interval between successive recording media. The image forming unit forms a test image at a space between successive recording-medium contact regions of the intermediate transfer member at which the recording medium contacts the intermediate transfer member. A travel distance of the intermediate transfer member from the detection position on the intermediate transfer member to the secondary transfer portion in a traveling direction thereof is shorter than the space between the successive recording-medium contact regions.

摘要： A sheet feeder, which is included in an image forming apparatus, includes a sheet loader on which a sheet is loaded, a sheet feeding body to feed the sheet from the sheet loader, and a sheet separator disposed to contact the sheet feeding body. The sheet is fed at a first average sheet feeding speed at which the sheet feeding body is in contact with the sheet separator without holding the sheet with the sheet separator. The sheet is fed at a second average sheet feeding speed at which the sheet feeding body is holding the sheet with the sheet separator. The first average sheet feeding speed is set smaller than the second average sheet feeding speed.

摘要： A sheet feeder includes a feeding member to contact a sheet and feed the sheet downstream in a sheet conveyance direction, a friction pad disposed facing the feeding member to contact the feeding member, and a receiving table including a pad mount to hold a side of the friction pad opposite a nip between the friction pad and the feeding member. The friction pad includes a fixed range secured to the pad mount upstream from the nip and a movable range extending downstream the nip in the sheet conveyance direction. A first friction force of the pad mount to act on the movable range of the friction pad is smaller than a second friction force of the sheet to act on the movable range of the friction pad.

摘要： An image forming apparatus includes an image bearer, an image forming device to form an image on the image bearer, a transfer device to transfer the image formed on the image bearer onto a sheet, a storage to store the sheet, a sheet feeder to convey the sheet one by one to the transfer device, and a slip amount prediction controller. The slip amount prediction controller calculates a predicted slip amount between the sheet feeder and the sheet before forming the image and, subsequently calculates an interval between images based on the predicted slip amount. The slip amount prediction controller controls the image forming device based on the calculated interval between images to form the image on the image bearer.
