A transport device includes: a first rotating body including a shaft portion, a cylindrical portion on an outer periphery of the shaft portion, and a recessed portion in an outer surface of the cylindrical portion; a second rotating body capable of moving from the first rotating body while contacting an outer surface of the first rotating body and nipping a recording medium; a transport unit that includes a holding portion that holds the recording medium, and that transports the recording medium by moving the holding portion in a rotation direction of the first rotating body while the holding portion is disposed in the recessed portion; and a moving mechanism including a cam portion on a side of the cylindrical portion and a contact portion connected to the second rotating body and that comes into contact with the cam portion to separate the second rotating body from the first rotating body.

Transport device, fixing device, and image forming apparatus

An image forming apparatus includes: a rotating body having a recess in an outer peripheral surface thereof; a sprocket provided coaxially with the rotating body to rotate integrally with the rotating body; a chain having plural links, the chain being wound around the sprocket to circulate in a circulating direction so as to shift from a rotary movement in which the chain rotates in an arc shape conforming to an outer periphery of the sprocket along with the sprocket, to a linear movement; a holder fixed to at least one link of the links of the chain, the holder being configured to hold a leading end portion of a recording medium, the holder being configured to transport the recording medium by performing the rotary movement along with the rotating body and the chain in a state of (i) holding the leading end portion of the recording medium placed on the outer peripheral surface of the rotating body and (ii) being located in the recess, and then shifting to the linear movement along with the chain; and an image forming unit configured to form an image on the recording medium placed on the outer peripheral surface of the rotating body, in which a holding position where the holder holds the recording medium is arranged downstream of an upstream roller of rollers of a most downstream link in the circulating direction among the at least one link to which the holder is fixed.

A drum member includes: a substantially cylindrical drum body having a hollow part extending in an axial direction; a sheet member wound on the drum body; an adjusting mechanism configured to adjust tension in the sheet member, the adjusting mechanism including a moving member that holds an end of the sheet member in a circumferential direction and moves in a depth direction of the hollow part, and a fixing member that fixes the moving member to the drum body; and one or more positioning members that position the moving member such that the moving member does not move in the circumferential direction of the drum body when the moving member is fixed with the fixing member.

Drum member and image forming apparatus

A jacket includes: a first layer that is on a cylinder body side when the jacket is attached to a rotating cylinder body; and a second layer that is a layer located on a side opposite to the cylinder body with respect to the first layer, has a hardness lower than that of the first layer, and does not exist at a position where at least one of end edges of the cylinder body in a rotation axis direction is located inward of the first layer in the rotation axis direction.

Jacket, transfer device, and image forming device

A transfer member includes: an inner layer; an outer layer provided on an outer periphery of the inner layer; and a surface layer provided on an outer periphery of the outer layer, both end portions of the surface layer in circumferential directions extending in the circumferential directions from both end portions of the outer layer in the circumferential directions.

A recording-medium transport device includes: a rotating first and second member, the first and second member forming a nip area therebetween and transporting a recording medium while nipping; a gripping member that grips the recording medium; a separating member that separates the recording medium passing through the nip area from the first or second member; and a control mechanism that controls contact and separation between the first and second member and opening and closing the gripping member where, in a first section, the gripping member passes between the first and second member, the first and second member are separated, and the gripping member is opened to release the recording medium until the first and second member come into contact with each other and, in a second section subsequent to the first section and before the recording medium reaches the separating member, the gripping member opens wider than the first section.

A belt-type transport device includes a belt, a pressure unit, a nip forming unit, a belt stretching roller, an inclination controller, a contact unit, and a support unit. The belt is an endless belt, has an outer circumferential surface and an inner circumferential surface, and is to be rotated. The pressure unit is in contact with the outer circumferential surface of the belt. The nip forming unit presses the belt against the pressure unit so as to form a nip through which a recording medium is to be transported. The belt stretching roller is disposed inside the belt and stretches the belt. The inclination controller controls inclination of the belt stretching roller. The contact unit is provided along a width direction of the belt and is in contact with the inner circumferential surface of the belt. The support unit supports the contact unit such that the contact unit is able to follow inclination of the belt which is changed due to the inclination of the belt stretching roller.
