Patent ID: 7883201

Claim:
An image forming apparatus comprising: a conveyance device which conveys an ejection receiving medium; an ejection head which ejects and deposits droplets of liquid on the ejection receiving medium conveyed by the conveyance device, the deposited droplets of the liquid constituting an image on the ejection receiving medium, wherein the following condition is satisfied: γ S ≧γ L , where γ S is a surface energy of the ejection receiving medium, γ L is a surface energy of the liquid; and a controller that controls the ejection so that the following conditions are satisfied: d ≧√{square root over (2)}× l ; and 2 × γ S × ( d 2 ) 2 - ( l 2 ) 2 ≥ d × γ L where d is a diameter of each of the droplets of the liquid deposited on the ejection receiving medium, and l is a maximum of a resolution pitch of the image.
