IMAGE FORMING APPARATUS
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
An image forming apparatus includes: a circulating member that is a part of a transport path that transports a recording medium; a holding member that is fixed to the circulating member, circulates, and holds a leading end portion of the recording medium; an image forming section that forms an image on the recording medium at an image forming position in a circulation path of the circulating member; and a feeding section that feeds out the recording medium to a holding position where the holding member holds the leading end portion of the recording medium. When a circulation velocity Vg is defined as a velocity at which the circulating member circulates the holding member, a transport velocity of the recording medium is reduced from a first transport velocity V1, which is higher than the circulation velocity Vg, to a second transport velocity V2, which is lower than the first transport velocity V1, before the leading end portion of the recording medium enters the holding position.
IMAGE FORMING APPARATUS
An image forming apparatus includes: a holding unit that holds a recording medium transported; a circumferential rotation unit that circumferentially rotates with the holding unit fixed, and constitutes part of a transport path along which the recording medium is transported; an image former that forms an image on the recording medium at an image formation position on a circumferential rotational path of the circumferential rotation unit; a pass point at which the recording medium is passed on the circumferential rotational path; and a receiving point which is provided on a same side as the pass point with respect to the image formation position, and at which the recording medium is received from the circumferential rotational path.
IMAGE FORMING APPARATUS
An image forming apparatus includes plural rotating members that are rotatable; an annular circulating member that is wound around the plural rotating members and circulates when the rotating members rotate; a retaining member attached to an attaching portion of the circulating member and that circulates together with the circulating member, the retaining member being configured to retain a recording medium in an area where the attaching portion comes into contact with one of the rotating members; an image forming section that forms an image on the recording medium at an image forming position defined on a circulation path along which the circulating member circulates; a delivering unit that delivers the recording medium to a retaining position where the recording medium is to be retained by the retaining member; a detector that detects rotation of the one rotating member; and a controller that controls delivery of the recording medium from the delivering unit to the retaining position, the delivery being controlled with reference to information detected by the detector.

RECORDING MEDIUM TRANSPORT DEVICE AND IMAGE FORMING APPARATUS
A recording medium transport device includes: a circulating member that forms a part of a transport path for transporting a recording medium; a holding member that is fixed to the circulating member and thereby circulates and holds a front end portion of the recording medium; plural transport cylinders around which the circulating member is suspended and having a recessed part in which the holding member is stored; and a selection part that selects any one of the plural transport cylinders. A mode for stopping the selected one of the plural transport cylinders so that the recessed part of the selected one of the plural transport cylinders is located at a maintenance position is prepared.
Devices, systems, and methods for controlling airflow through vacuum platen of printing systems via airflow zones
A printing system comprises printheads to eject ink to a deposition region. Print media are held by vacuum suction against a movable support surface, which moves over a vacuum platen. The vacuum platen comprises platen holes through which the vacuum suction is communicated. An airflow control system comprises airflow zones, each comprising a group of the platen holes, a duct, and a valve, the duct and the valve being arranged to selectively control vacuum suction through the group of the platen holes. For each of the printheads, at least one of the airflow zones is located under the respective printhead. Thus, airflow through platen holes under the printheads can be selectively controlled by selectively controlling the vacuum suction in the airflow zones.
Continuous sublimation transfer method using a vacuum suction roller
The present invention relates to a continuous printing apparatus using a vacuum suction roller, and it is to provide a continuous printing apparatus and method using a vacuum suction roller capable of reducing costs and improving productivity by continuously printing on the surface of a woven fabric using the vacuum suction roller.
TRANSPORT DEVICE AND IMAGE FORMING APPARATUS
A transport device includes: a rotating member that rotates; a circulating member that is loop-shaped and wrapped around the rotating member, the circulating member being circulated by rotation of the rotating member; and a pair of pinching members attached to an attachment portion of the circulating member and circulated together with the circulating member, the pair of pinching members changing from a separated state, in which the pair of pinching members are separated from each other, to a closely positioned state to pinch a transport object that has entered a space between the pair of pinching members in the separated state. The attachment portion of the circulating member is in contact with the rotating member when the transport object starts to enter the space between the pair of pinching members in the separated state.
