    摘要： A drive transmission device includes a gear train and a movable gear locking device. The gear train transmits rotational drive to a drive target, and includes a first gear train forming a first transmission path for transmitting the drive to the target, a second gear train forming a second transmission path for transmitting the drive to the target as drive opposite in rotation direction to the drive transmitted by the first gear train, and a movable gear movable between a first drive transmission position whereat the movable gear forms a part of the first gear train to transmit the drive to the target and a second drive transmission position whereat the movable gear forms a part of the second gear train to transmit the drive to the target. The movable gear locking device locks the movable gear at an idle position.

    摘要： A drive transmitter includes a first unit including a coupling portion having grooves spaced at an angle of 180 degrees in the rotational direction, and a second unit having projections spaced at an angle of 180 degrees in the rotational direction. The projections are configured to be inserted into the grooves of the coupling portion. The coupling portion has a guiding portion and a non-guiding portion. The guiding portion is sloped, with a height from a bottom face of the grooves decreasing in the rotational direction of the first unit, and is configured to guide the projections to the grooves. The non-guiding portion is disposed at a point symmetrical position to the guiding portion to an axial center of the first unit. One of the projections is not in contact with the non-guiding portion while another one of the projections is in contact with the guiding portion.

    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.
