    Abstract: An image forming apparatus includes an application device. The application device has an application roller to apply a treatment liquid onto a recording medium before an image is formed on the recording medium. The application roller has a core member serving as a rotation shaft of the application roller and an elastic surface member disposed around the core member. The core member has a plurality of convex ring portions formed along a circumferential direction of the core member around a circumferential surface of the core member and a plurality of concave ring portions formed between the plurality of convex ring portions. The convex ring portions and the concave ring portions are alternately arranged.

    Abstract: A liquid discharge apparatus includes a carriage (1), a liquid discharge head (300, 300C, 300K, 300M, 300Y, 300S, 300W) having a discharge port (P1, P2), a first driver (92), and a second driver (93). The carriage is movable along at least one of a first axis (X) and a second axis (Y) intersecting the first axis. The liquid discharge head is held by the carriage and discharges a liquid from the discharge port toward an object (100) in a direction along a third axis (Z) intersecting the first axis and the second axis. The first driver moves the carriage along the third axis. The second driver moves the liquid discharge head along the third axis relative to the carriage.

    Abstract: A liquid discharge apparatus includes a head to discharge a liquid containing a solvent from a discharge port toward an object, a concentration detector to detect a vapor concentration of the solvent, and circuitry to causes the head to discharge the liquid from the discharge port while moving the discharge port of the head in a movement direction perpendicular to a discharge direction to discharge the liquid. When the vaper concentration is equal to or higher than a first threshold, the circuitry stops moving the head in the movement direction and causes the head to stop discharging the liquid from the discharge port. When the vaper concentration is less than a second threshold, the circuitry resumes moving the head in the movement direction from a stop position where the head stops moving in the movement direction and causes the head to resume discharging the liquid from the discharge port.

    Abstract: A liquid discharge apparatus includes a head including a discharge port. The head discharges a liquid from the discharge port toward an object. The liquid discharge apparatus further includes a liquid receiving surface that receives the liquid discharged from the discharge port, a contact part that contacts the discharge port, a moving unit that holds at least one of the liquid receiving surface and the contact part, and a holder. The moving unit is movable between a facing position where at least one of the liquid receiving surface and the contact part faces the discharge port and a position where the liquid receiving surface and the contact part do not face the discharge port. The holder movably holds the discharge port of the head in a discharge direction to discharge the liquid.
