An image forming device includes an image carrier, a transfer member, a fixing device, a conveyance member, and a controller. The transfer member forms a transfer nip that transfers an image carried on the image carrier to a recording medium. The fixing device fixes the image on the recording medium. The conveyance member is located downstream of the transfer member in a conveyance direction of the recording medium and feeds the recording medium to the fixing device. The controller variably controls position of the conveyance member.

An image forming device includes: a conveyance path that conveys a printing medium; an image former that is arranged in a first place in the middle of the conveyance path, forms an image on one surface of the printing medium, and fixes the formed image by heating; a cooler that is arranged in a second place downstream in a conveyance direction from the first place in the middle of the conveyance path, and cools the printing medium by blowing air for cooling to the printing medium; and a reader that is arranged in a third place downstream in the conveyance direction from the second place in the middle of the conveyance path, and reads the image formed on the printing medium, wherein between the first place and the second place of the conveyance path, one or a plurality of guide members is provided, and a guide member is not provided.

A static elimination device includes: a first static elimination member that makes contact with a medium that is transported; a second static elimination member arranged such that the medium is inserted between the first static elimination member and the second static elimination member; and a power source that applies a voltage to at least one of the first static elimination member or the second static elimination member, in which at least one of the first static elimination member and the second static elimination member has an elastic body.

An image forming apparatus includes a transfer unit forming a transfer nip portion, a fixing unit forming a fixing nip portion, and first and second belt suction conveyance units to suck a sheet onto a first belt and a second belt, respectively. The fixing nip portion is arranged at a position above the transfer nip portion. In a sheet conveyance direction, an upstream end portion of the first belt in the first belt suction conveyance unit is provided below the transfer nip portion, a downstream end portion of the first belt is provided above an upstream end portion of the second belt in the second belt suction conveyance unit, and a downstream end portion of the second belt is provided below the fixing nip portion. The first and second belts are inclined from a lower position to an upper position from upstream to downstream in the sheet conveyance direction.

An image forming apparatus includes a transfer member, a fixing member, a guide member, and an attraction member. The transfer member transfers a developer to a medium. The fixing member fixes onto the medium the developer transferred to the medium. The guide member is disposed between the transfer member and the fixing member to guide the medium. The attraction member attracts the developer through the opening. An opening is located upstream of the guide member in a medium transport direction.

A mounting member to be mounted on a member that moves in a traveling direction includes: a rectangular sheet member; and an attachment portion having a first surface bonded to one end portion of a reverse surface of a downstream side portion of the sheet member in the traveling direction, the attachment portion being detachably attached to an attachment-receiving portion and having a surface facing a direction different from a direction of the first surface and bonded to the sheet member.

A transport device includes: a first transport body; a second transport body that is movable between a contact position and a separate position with respect to the first transport body and that nips a transported material with the first transport body at the contact position; and a transport section that includes a holder to hold a leading end portion of the transported material and that transports the transported material toward a nip region where the first transport body and the second transport body nip the transported material in a state in which the second transport body is located at the separate position. After holding of the leading end portion by the holder for the transported material transported by the transport section has been released, the second transport body nips the transported material with the first transport body and transports the transported material.

An image forming apparatus includes: a forming part that forms an image on a recording medium; a fixing part that fixes the image formed on the recording medium; a revolving part having a revolving member stretched over multiple rotary members, the revolving member revolving between the forming part and the fixing part to transport the recording medium from the forming part to the fixing part; a feed part that feeds the recording medium to the forming part; a discharge part that discharges the recording medium to which the image has been fixed in the fixing part; a branch part that is provided so as to be split from the discharge part and along which the recording medium, to one side of which the image has been fixed, is transported to the feed part after switching the leading end and the trailing end of the recording medium; a first housing accommodating the forming part, the fixing part, and the revolving part; and a second housing connected to the first housing and accommodating the feed part, the discharge part, and the branch part.

A cylinder member includes: a cylinder body having a cross section and including a dent portion; a sheet member wrapped around the cylinder body and including a metal layer contacting the cylinder body and an outer layer; a first attachment member on a sheet member first end portion and removably attached to the dent portion; a second attachment member on a metal layer end portion protruding from the outer layer in the circumferential direction at a sheet member second end portion, the second attachment member being removably attached to the dent portion; a tension-applying mechanism pulling the second attachment member in a dent portion depth direction to apply tension to the metal layer; a projection on one of the second attachment member and metal layer end portion; and a fitting portion on other one of the second attachment member and the metal layer end portion and fitted to the projection.

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.
