An image forming apparatus includes an image forming device, a rotatable conveying member, and a suction device. The image forming device forms an image on a continuous recording medium. The conveying member has a hollow drum shape. The conveying member conveys the continuous recording medium. The suction device is disposed inside the hollow drum shape of the conveying member. The suction device sucks the continuous recording medium through the conveying member in a fixed region in which the continuous recording medium and the conveying member are in contact with each other.

Image forming apparatus

A device includes a temperature control member and a linearly-contact member. The temperature control member has an outer peripheral surface to contact a conveyed substrate to which liquid is applied, and heats or cools the substrate. The linearly-contact member contacts the substrate and the temperature control member on an upstream side from a contact position between the substrate and the temperature control member in a conveyance direction of the substrate.

Device and liquid discharge apparatus

A liquid discharge apparatus includes a liquid discharge head including a nozzle face including a nozzle configured to discharge a liquid, a head cap configured to cover the nozzle face of the liquid discharge head, a buffer tank disposed downstream from the head cap in a direction of collection of the liquid from the liquid discharge head and configured to temporarily store the liquid, a communication passage coupling the head cap and the buffer tank, and a heater configured to heat the liquid stored in the buffer tank. The quid discharge apparatus further includes a heat source configured to generate heat and a heat introduction passage coupling the heat source with the buffer tank, to introduce exhaust heat from the heat source into the buffer tank.

Liquid discharge apparatus

An apparatus according to one aspect of the present disclosure includes a temperature controlling member configured to heat or cool a conveyed substrate to which a liquid is applied, the conveyed substrate contacting an outer peripheral surface of the temperature controlling member; and an upstream inlet air unit configured to draw air between the substrate and the temperature controlling member, the upstream inlet air unit being provided upstream of a contact location of the substrate with the temperature controlling member, in a conveying direction.

Apparatus, inlet air unit and liquid discharging apparatus

A liquid discharging device includes a carriage carrying a head configured to discharge a liquid onto a target, the liquid including an ink, the ink consisting water, an organic solvent, a coloring material, and a plurality of polysiloxane compounds, a driving unit configured to move the carriage and the target relatively to each other, a measuring unit configured to measure the distance between the carriage and the target, an image-capturing unit configured to capture a target image, and a setting unit configured to set a liquid discharging performance of the head based on a measurement result obtained by the measuring unit and the target image obtained by the image-capturing unit.

Liquid discharging device and liquid discharging method

A line head type liquid discharge apparatus includes a treatment liquid applying device, a first discharging device, a heating device, and a second discharging device. The treatment liquid applying device applies a treatment liquid to a non-permeable base material. The first discharging device discharges a first ink containing an organic solvent onto the non-permeable base material to which the treatment liquid has been applied. The heating device heats, with an infrared ray, the non-permeable base material onto which the first ink has been discharged. The second discharging device discharges a second ink containing an organic solvent onto the non-permeable base material heated by the heating device. A content ratio of the organic solvent contained in the first ink is higher than a content ratio of the organic solvent contained in the second ink.

Liquid discharge apparatus and liquid discharge method

A dryer includes a conveyor to convey a film including a first surface onto which a liquid is applied, a noncontact heater to heat the first surface of the film conveyed by the conveyor without contacting the first surface, a contact heater to contact and heat a second surface of the film opposite the first surface, and circuitry to set a first heating temperature of the contact heater less than 85&#xb0; C. and set a second heating temperature of the noncontact heater to be 30&#xb0; C. to 90&#xb0; C. higher than the first heating temperature.

Dryer, liquid discharge apparatus, drying method, and inkjet recording apparatus

A liquid discharging device detects, among a plurality of nozzles of a liquid discharging head, a normal-discharging nozzle and a false-discharging nozzle, selects whether to recover discharging performance of the false-discharging nozzle by a cleaner or to compensate deterioration in an image caused by the false-discharging nozzle by a compensator using the normal-discharging nozzle according to the detected number of consecutive false-discharging nozzles, and performs operation according to the selection.
