The fixed body includes a through hole, and an opposing face is formed at a periphery of the through hole in a direction orthogonal to the optical axis direction and opposing the movable body. The opposing face has a protrusion protruding toward the movable body side at a peripheral edge of the through hole, and a recess at a periphery of the protrusion and recessed toward the movable body side. The movable body includes an opening to let light from the lens pass through and a flat face formed at a periphery of the opening in a direction orthogonal to the optical axis direction and disposed opposing the protrusion and the recess.

An image forming apparatus includes a holding body that holds a formed image; a transport unit that transports a recording medium in a state where a tip of the recording medium is grasped by a grasping portion; a transfer cylinder that has a substantially circular cross section, and that includes a concave portion that accommodates the grasping portion in a direction substantially orthogonal to a rotation direction and transfers an image on the holding body to the recording medium transported by the transport unit by interposing the recording medium transported by the transport unit between the transfer cylinder and the holding body; and an imparting portion that imparts a transport load to the recording medium that is transported to a transfer position at which the image on the holding body is transferred to the recording medium.

Image forming apparatus

A lens driving device, a camera device, and an electronic apparatus are provided that include a base not susceptible to thermal deformation. A lens driving device includes a movable body including a lens support body, and a base configured to support the movable body so as to be able to move in an optical axis direction of a lens. The base includes a base body formed from a resin and having a rectangular plate shape when viewed along the optical axis direction of the lens, and a ring shaped metal member embedded in the base body. The metal member is formed with a projecting portion facing outward at each side of a rectangular shape and exposed from the base body.

A lens driving device being capable of securing smooth movement of a lens support body includes a guide mechanism. The guide mechanism includes a guide groove and a guide projection for fitting into the guide groove so as to be able to slide. The guide groove includes a bottom face formed in a planar shape. In an XYZ orthogonal coordinate system wherein a sliding direction is an X direction and a height direction is a Z direction, the guide projection includes a Z direction end face opposing the guide groove bottom face. A cross-section profile of the Z direction end face sectioned along an XZ plane is formed with a curved shape convex on the guide groove bottom face side, and a cross-section profile of the Z direction end face sectioned along a YZ plane is formed with a curved shape convex on the guide groove bottom face side.

An image forming apparatus includes: a holding body configured to hold a formed image; a conveyance unit configured to convey a recording medium with a leading end of the recording medium gripped by a gripping portion; and a transfer body including a recessed portion that accommodates the gripping portion and is provided along a direction substantially orthogonal to a rotational direction, configured to sandwich the recording medium conveyed by the conveyance unit between the transfer body and the holding body to transfer an image on the holding body to the recording medium conveyed by the conveyance unit, and including a slope surface provided at a leading end of a portion of an outer circumference not including a portion where the recessed portion is provided, the leading end being on a front end side in the rotational direction, a distance from the slope surface to a rotational center becoming larger toward a downstream side in the rotational direction.

Provided is an image forming apparatus including: an annular transfer belt having an outer surface on which an image is transferred; a transferring unit including a transfer cylinder having a transfer area that sandwiches a recording medium with the outer surface of the transfer belt to transfer the image from the outer surface of the transfer belt to the recording medium, and a pair of first rotating bodies disposed on both axial end sides of the transfer cylinder; a pair of circulating members each being wound around the first rotating body and being circulated by rotation of the first rotating bodies; and a holding unit attached to the circulating members, the holding unit configured to hold the recording medium, transport the recording medium with circulation of the circulating members, and pass the recording medium through the transfer area.

A lens driving device includes a lens support, a first moving member plate and a second moving member plate that surround around a periphery of the lens support, wherein the first moving, member plate is supported so as to be freely movable relative to the second moving member plate by a first support mechanism that includes a first support protrusion and a first guide recess into which the first support protrusion is fitted, the lens support is supported so as to be freely movable relative to the first moving member plate by a second support mechanism that includes a second support protrusion and a second guide recess into which the second support protrusion is fitted.

A transfer member includes: an inner layer; and an outer layer that is adhered to the inner layer and has a hardness lower than a hardness of the inner layer.

Transfer member, transfer drum, and image forming apparatus

A transfer device includes a transfer drum that rotates in conjunction with a fixing roller, a transfer belt that transfers an image onto a medium while rotating along with the transfer drum in a state where the medium is nipped between the transfer belt and the transfer drum, a pressing member that is disposed in a space enclosed by the transfer belt, and a switching unit that moves the pressing member and switches between a pressed state in which the transfer belt is pressed against the transfer drum and a separated state in which the transfer belt is separated from the transfer drum.
