A snap ring is set to a set portion of a shaft of a rotator from a direction orthogonal to an axial direction of the shaft. The snap ring includes a first arcuate portion and a second arcuate portion facing each other, being elastically deformable in directions away from each other, holding the set portion by elastic deformation restoring force. One ends of the first and second arcuate portions are away from each other to form an insertion portion to insert the set portion. When the snap ring is not used, the first arcuate portion has a same radius of curvature as the second arcuate portion and the set portion, and a center of curvature closer to the second arcuate portion than the first arcuate portion, and the second arcuate portion has a center of curvature closer to the first arcuate portion than the second arcuate portion.

A method for adapting a printer for operating with more colours, the printer including an inner framework and a dispenser assembly associable with said framework, includes the steps of application of at least one first quick release connector for electric cables at the dispenser assembly; and application of at least one corresponding second quick release connector at the inner framework of the printer.

In an image forming apparatus, if a path for transferring heat generated by a drive integrated circuit to a frame (a heat dissipation plate) of an apparatus main body has a point that divides the path, foreign matter such as dirt and dust can be caught at the point, so that heat dissipation efficiency can decrease due to presence of such foreign matter. Therefore, a configuration is provided in which a drive integrated circuit and a frame (a heat dissipation plate) provided in a cover are connected by a heat transfer member, so that a heat transfer path from the drive integrated circuit to the frame has no point that divides the path.

A method of manufacturing a frame unit from a first unit. The first unit includes a first image carrying member, a supporting member supporting the first image carrying member, and a frame to which the supporting member is adhered. The first image carrying member includes a first edge portion member, and the first edge portion member includes a first restricted portion. The supporting member includes a bearing engaging with the first edge portion member so that the first image carrying member is rotatable about a rotational axis. The frame includes a first restricting portion restricting movement of the first image carrying member. The method includes separating in which the first image carrying member is separated from the supporting member while in a state in which the supporting member is adhered to the frame.

A drive force transmission mechanism includes a drive pulley, a driven pulley and an endless belt. The endless belt is wound around the drive pulley and the driven pulley and transmits a rotation of the drive pulley to the driven pulley. At least one of the drive pulley and the driven pulley has a protruding part protruding outwardly in a radial direction around an outer circumferential face of the drive pulley or the driven pulley. The belt is a nonmagnetic metal belt having an outer circumferential face and an inner circumferential face. The outer circumferential face has a surface roughness smaller than a surface roughness of the inner circumferential face.

Therefore, a configuration is provided in which a drive integrated circuit and a frame (a heat dissipation plate) provided in a cover are connected by a heat transfer member, so that a heat transfer path from the drive integrated circuit to the frame has no point that divides the path.

A cleaning apparatus includes an endless belt configured to bear a toner image, a rotary member configured to be wound around by the belt, and configured to rotate integrally with the belt, a bearing configured to rotatably support the rotary member, a cleaning unit configured to come into contact with a surface of the belt and collect an adhering matter adhered onto the surface, an urging member configured to urge the cleaning unit toward the surface of the belt, and a support member configured from a single member and including a first supporting portion, a second supporting portion, and a third supporting portion. The first supporting portion rotatably supports the belt via the bearing and the rotary member. The second supporting portion pivotably supports the cleaning unit. The third supporting portion supports the urging member.

A unit accommodation apparatus includes a first unit and a second unit that are to be installed into and removed from an apparatus body through an opening in an installation-removal direction and are held by a unit holder. The unit holder includes a first positioner that is disposed opposite one lateral end of the first unit and the second unit and is detachably attached to the first unit and the second unit. A second positioner is disposed opposite another lateral end of the first unit and the second unit and holds the first unit and the second unit in a state in which the first unit and the second unit are detachably attached to the second positioner. The first positioner and the second positioner secure a relative position of the first unit relative to the second unit in a direction parallel to a hypothetical orthogonal plane perpendicular to the installation-removal direction.

An image forming apparatus includes the following: an image forming portion; a first metal side plate and a second metal side plate provided opposite each other with respect to the image forming portion; an antenna for communicating with external equipment; a housing including a top cover that is provided above the first metal side plate and the second metal side plate in a vertical direction, and a side cover that is provided on an outer side opposite to an inner side where the image forming portion is provided with respect to the first metal side plate, wherein the image forming apparatus further includes a support member provided on the first metal side plate, the support member including a housing support portion that supports at least one of the top cover and the side cover, and an antenna support portion that supports the antenna.

Proposed are a home port and a substrate processing apparatus using the same. The home port is installed in the substrate processing apparatus to temporarily mount a nozzle for discharging a process liquid to a substrate, and includes a main body having a space therein, a nozzle holder provided at an upper portion of the main body and configured to mount the nozzle, an inclined surface formed below the nozzle holder in the space, a first supply pipe configured to discharge a rinse liquid to a tip of the nozzle, a second supply pipe configured to inject the rinse liquid into the main body, a conductive wire configured to electrically connect the inclined surface and the first supply pipe, and a first switch installed on the conductive wire.
