A conveyance device includes: a conveyance unit that conveys a material to be conveyed; a guide unit that guides the material to be conveyed, the guide unit being movable between a first position at which a first conveyance path is formed and a second position at which a second conveyance path is formed; a driving unit that drives the conveyance unit and the guide unit; a restriction unit that comes into contact with the guide unit moving in a moving direction from the second position to the first position at the first position by a driving force of the driving unit to restrict the movement of the guide unit in the moving direction; and a blocking unit that blocks transmission of the driving force of the driving unit to the guide unit when a moving load greater than or equal to a predetermined load acts on the guide unit moving in the moving direction.

Conveyance device and image forming apparatus

A transport device includes a transport member that transports a recording medium while adjusting a leading end of the recording medium, and a guide member that is disposed upstream from the transport member in a transport direction of the transport member to guide the recording medium to the transport member along a transport path, the guide member being rotatable in a direction to open the transport path while having a downstream portion in the transport direction of the transport member serving as an axis.

Transport device and image forming apparatus

A rotating device includes: a first rotating body capable of forward rotation; a second rotating body capable of forward rotation and reverse rotation; a drive unit outputting drive forces in a forward rotation direction and a reverse rotation direction; and a transmission mechanism transmitting the drive force in the forward rotation direction output from the drive unit to the first rotating body and the second rotating body to rotate the first rotating body and the second rotating body in the forward direction and transmitting the drive force in the reverse rotation direction output from the drive unit to the first rotating body and the second rotating body to rotate the first rotating body in the forward direction and rotate the second rotating body in the reverse direction.

Rotating device, transporting device, and image forming apparatus

A rotating device includes: an opening-closing portion supported so as to be openable and closable with respect to a support body; a drive unit provided on the support body; a first rotating body provided on the support body and rotated by a drive force of the drive unit; a driven portion provided in the opening-closing portion; a second rotating body provided in the opening-closing portion, rotated by a transmitted rotational force, and transmitting the rotational force to the driven portion; and an annular body formed in an annular shape, wound around the first rotating body and the second rotating body, maintaining the winding state in both an open state and a closed state of the opening-closing portion, and transmitting the rotational force of the first rotating body to the second rotating body.

A manual sheet feeding device includes: a sheet feeding rotary body configured to separate and feed recording media placed on a manual sheet feeding unit one by one; a shielding unit configured to cover an outer side surface of the sheet feeding rotary body, the shielding unit having an aperture for exposing at least a part of the sheet feeding rotary body to an outside; and an opening and closing unit configured to open and close the aperture of the shielding unit.

Manual sheet feeding device and image forming apparatus

A drive transmission apparatus includes a drive source; a rotating member that rotates by drive from the drive source; a structure that is attachable to and detachable from a drive transmission apparatus body and at least partly houses a transmission mechanism that transmits the drive from the drive source to the rotating member; a support member that has first and second surfaces, and supports the structure; and a coupling member that is fixed to the support member by a first fixing tool and to the structure by a second fixing tool, and couples the structure with the support member. The coupling member includes a first attachment portion to which the first fixing tool is attached from a side of the first surface of the support member, and a second attachment portion to which the second fixing tool is attached from a side of the second surface of the support member.

Drive transmission apparatus and image forming apparatus

An image forming apparatus includes an image forming unit that forms an image on a recording material, a transport unit that transports the recording material, using a driving member which rotates and plural rotating parts which are aligned in an axial direction of the driving member and are disposed in contact with the driving member so as to rotate by receiving a driving force from the driving member, a support member that is shared by the plural rotating parts and supports the plural rotating parts from a side opposite to a side where the driving member is disposed, and a biasing unit that biases the support member toward the driving member.
