Patent ID: 8109595

Claim:
A droplet ejection apparatus comprising: a droplet ejection head that ejects droplets; a conveying member that retains a recording medium and conveys the recording medium with facing the recording medium to the droplet ejection head; a coating member that coats the conveying member with a coating liquid, the coating liquid having a repellant property to the liquid ejected from the droplet ejection head; and a cleaning member that cleans the conveying member, the droplet ejection apparatus satisfying the following formulae (1) L3>L1, L2>L1 (1) wherein, in the formulae (1): L1 is the maximum width of a region, in the direction orthogonal to the conveying direction, of the ink droplet ejecting of the droplet ejection head; L2 is the maximum width of a region, in the direction orthogonal to the conveying direction, of coating the coating liquid on the conveying member by the coating member; and L3 is the maximum width of a region, in the direction orthogonal to the conveying direction, of the cleaning of the conveying member by the cleaning member, and the droplet ejection apparatus satisfying the following formulae (A) and (B) γ o <γ b (A) γ o <γ i (B) wherein, in formulae (A) and (B): γ o is a surface tension of the coating liquid; γ b is a critical surface tension of the conveying belt; and γ i is a surface tension of the ink.
