A belt driving device includes plural rotating members around which a belt member extends, each rotating member rotating about a rotating shaft; and contact members disposed at both sides of the belt member in a width direction. The rotating members include a first rotating member, having a dimension less than a width of the belt member in a direction of the rotating shaft. Each contact member has a first contact point at which the contact member contacts the belt member and a second contact point closer to a corresponding one of the end portions in the width direction than the first contact point and at which the contact member contacts the belt member such that an angle between the contact member and the rotating shaft at the second contact point is greater than an angle between the contact member and the rotating shaft at the first contact point.

Belt driving device, transfer device, and image forming apparatus

A moving apparatus includes: an exposure unit that forms a latent image by exposure; a support unit that supports the exposure unit so that the exposure unit is displaceable, a guide groove guiding a movement of the support unit to move the exposure unit between an exposure position and a retracted position; a first link unit that includes a first shaft portion, and a second shaft portion that swings about the first shaft portion to transmit force used to move the exposure unit; a second link unit that connects the support unit and the second shaft portion of the first link unit; and a coupling shaft that connects the support unit and the second link unit and is guided by the guide groove.

Moving apparatus having exposure device

A moving mechanism includes a moving object to be moved between a first position and a second position where the moving object takes a stationary orientation different from a stationary orientation for the first position; a first projection and a second projection provided at different positions, respectively, on the moving object; a member having a first guiding groove that guides the first projection when the moving object is moved between the first position and the second position; and a member having a second guiding groove that guides the second projection when the moving object is moved between the first position and the second position, the second guiding groove having a different shape from the first guiding groove.

Image forming apparatus and exposure device moving mechanism including guiding grooves with different shapes

A link mechanism includes a rotatable link having a fulcrum pin on which the rotatable link rotates, and a connecting pin provided at a different position from the fulcrum pin; and a supporting member having a guiding groove along which the connecting pin of the rotatable link that is moved between two positions is guided, and a supporting groove in which the fulcrum pin of the rotatable link is rotatably supported. The guiding groove of the supporting member includes a long-side guiding portion shaped with a curvature that is greater than a curvature of a substantially arc shape defined by a radius corresponding to a distance between the fulcrum pin and the connecting pin of the rotatable link. The supporting groove of the supporting member is a substantially oblong groove extending in a direction intersecting a direction in which the long-side guiding portion of the guiding groove extends.

Link mechanism and image forming apparatus

An image forming apparatus includes: a first opening/closing member that can move between a first opening position in which the first opening/closing member opens an inside of a body of the image forming apparatus, and a first closing position in which the first opening/closing member closes the inside of the body of the image forming apparatus; a second opening/closing member that can move around a rotation shaft and between a second closing position in which the second opening/closing member closes an opening formed in the first opening/closing member, and a second opening position in which the second opening/closing member opens the opening, the second opening/closing member being removably attached to the body of the image forming apparatus; and a supported portion that is provided in the first opening/closing member so as to be supported on a support portion of the second opening/closing member, as defined herein.

Image forming apparatus having two opening and closing portions

An image forming apparatus includes a covering/not-covering member that is supported by an apparatus body so as to be movable between a not-covered position and a covered position; a transporting member that is mountable on and removable from the covering/not-covering member; a positioning member provided at the apparatus body; and an engaging member provided at the covering/not-covering member, the engaging member moving as the transporting member is moved relative to the covering/not-covering member by the positioning member, to engage an engage member and hold the covering/not-covering member at the covered position.
