A transport device includes a first rotary part that rotates; a second rotary part that contacts the first rotary part, that forms a pinch region where an object to be transported is pinched between the second rotary part and the first rotary part, and that rotates together with the first rotary part; and a positioning mechanism that positions the second rotary part with respect to the first rotary part. The positioning mechanism includes a swing part that supports one end portion side of the second rotary part, that is supported at one end portion side of the first rotary part, and that is swingable around a rotation center of the first rotary part; and a fixing section that fixes the swing part.

Transport device and image forming apparatus

An image forming apparatus includes: an apparatus body including an image former that forms an image on a recording material; a covering part that is provided in the apparatus body and leaves an inside of the apparatus body open by being opened in an opening direction with respect to the apparatus body; a reversing unit that is housed by the apparatus body and discharges part of the recording material on which the image is formed by the image former externally of the apparatus body, and reverses a transport direction of the recording material; and a guiding unit that is provided adjacent to a downstream side of the covering part in the opening direction, guides the recording material discharged through the apparatus body by the reversing unit, and when the covering part is opened with respect to the apparatus body, the guiding unit moves relatively with respect to the covering part in an opposite direction of the opening direction.

Image forming apparatus and recording material transport device

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.

Image forming apparatus and sheet transport device

A fixing device includes an endless belt, a fixing rotating body that fixes, in cooperation with the belt, a toner image formed on a recording medium nipped between the fixing rotating body and the belt while rotating in contact with the belt, a support member that supports a load with which the fixing rotating body nips the recording medium with the belt so as to form a nip portion to nip the recording medium between the belt and the fixing rotating body, a driving unit that circulates the belt in a state in which the fixing rotating body is separate from the belt, and a wind-on rotating body on which the belt is wound at a position adjacent to the support member on an upstream side in a direction of transport of the recording medium to the nip portion.

Fixing device and image forming apparatus

A fixing device includes a heater that transports a recording medium while rotating in a first direction and fixes an image formed on the recording medium to the recording medium by heating the image, a reducing member that rotates in a second direction different from the first direction, the reducing member and the heater contacting each other and rotating at different speeds, and the reducing member scratching an outer peripheral surface of the heater, and a moving device that moves the heater with respect to the reducing member in a direction of a rotational axis of the reducing member.
