Patent ID: 8764157

Claim:
An inkjet recording device, comprising: a recording head configured to eject droplets of ink; and a waste ink tray configured to receive the ink drained from the recording head, wherein a surface of the waste ink tray, which receives the ink, is made of an antibacterial agent containing resin composition, and a solubility of the antibacterial agent containing resin composition, which is measured by a measurement method (X), is 1.0 or higher and 3.0 or lower, the measurement method (X) including: preparing a test piece of the antibacterial agent containing resin composition, which is square in shape with length and width of 1 cm and a thickness of 0.3 cm; immersing the test piece into water based ink with a weight of 10 g in a 25° C./50% RH environment; measuring a mass W 1 of the test piece after one-month immersion; and obtaining the solubility of the antibacterial agent containing resin composition from a mass W 0 of the test piece before the immersion in the water based ink and the mass W 1 of the test piece after the immersion on the basis of an equation (a): solubility=(1 −W 1 /W 0 )×100 (a).
