A liquid composition includes an inorganic particle and a multivalent metal salt, wherein the liquid composition has a tacking force of 50 mN or less in an area of cast-coated paper where the liquid composition is applied in an amount of 0.12 mg/cmfor the cast-coated paper followed by heating at 80 degrees C. for 15 seconds.

Liquid composition, device for applying liquid composition, image forming device, and image forming method

An ink and processing liquid set contains a processing liquid to be applied to a recording medium, the processing liquid including a multivalent metal salt and an ink to be applied to an area of the recording medium where the processing liquid has been applied, the ink including a urethane resin, a styrene-acrylic resin, and a pigment, wherein the following relations are satisfied: 0.5&#x2264;B/C&#x2264;0.7, where B represents a static surface tension of the ink and C represents a static surface tension of the processing liquid; and 0.5&#x2264;E/D&#x2264;0.9, and 35 (mN/m)&#x2264;E&#x2264;55 (mN/m), where D represents a dynamic surface tension at 15 ms of the processing liquid and E represents a dynamic surface tension at 1500 ms of the processing liquid.

Ink and processing liquid set, image forming method, and image forming device

An image forming method includes applying white ink containing hollow resin particulate to a recording medium and contacting a heating roller having a diameter of 200 mm or less with a first surface of the recording medium.

Disclosed is a method of manufacturing an electromechanical transducer layer on a surface of a substrate, including discharging a solution including a source material to form the electromechanical transducer layer from a nozzle of a nozzle plate to coat the solution on the surface of the substrate while applying voltage between the nozzle plate and the substrate to charge the nozzle plate at a first polarity and the substrate at a second polarity opposite to the first polarity such that a split droplet split from a main droplet which is coated on the surface of the substrate becomes charged at the second polarity and is attracted and collected by the nozzle plate; and applying a heat treatment to the substrate on which the solution is coated to crystallize the solution to form the electromechanical transducer layer.
