Abstract
An imaging unit includes a support body; a photoconductor supported by the support body; a developing device supported by the support body to swing about a pivot arranged at a pivot portion, and including a development roller having a gap holding member that contacts a portion of the photoconductor; and a driven coupling member provided at a first end portion of the development roller, and removably coupled to a driving coupling member to which a rotational power is transmitted. The pivot portion is arranged so that the developing device swings toward the photoconductor by self weight. The driving or driven coupling member has at least three protruding portions that restrict rotation of the developing device when the members are coupled. The development roller rotates in a generation direction of an action that causes the developing device to swing toward the photoconductor when receives the rotational power and is rotationally driven.
