Patent ID: 8579429

Claim:
A droplet ejection device comprising: a first storing unit configured to store image data; a head configured to eject droplets onto a recording medium so as to form an image corresponding to the image data; a treating-agent application member configured to apply a treating agent to the recording medium; an extract unit configured to extract a part of the image as a specific image portion based on the image data; a control unit configured to control the treating-agent application member to apply the treating agent to a first section and a second section of the recording medium, wherein the specific image portion is formed in the first section, and at least a part of a non-specific image portion of the image other than the specific image portion is formed in the second section; a detection unit configured to detect a remaining amount of the treating agent; a first determining unit configured to determine whether or not the remaining amount is less than a first amount; a second storing unit configured to store a plurality of different extract conditions and a priority order of the extract conditions; and a second determining unit configured to determine whether or not the remaining amount is less than a second amount, which is less than the first amount, wherein, when the remaining amount is less than the first amount, the control unit is configured to control the treating-agent application member to apply the treating agent to the second section by an amount less than an amount of the treating agent that is applied to the second section when the remaining amount is not less than the first amount, wherein the extract unit is configured to extract, as the specific image portion, a part of the image that matches any one of the extract conditions, wherein, when the remaining amount is less than the second amount, and when the extract unit extracts a plurality of specific image portions corresponding to a plurality of different priorities of the extract conditions, the control unit is configured to control the treating-agent application member to apply the treating agent to a third section of the recording medium by an amount less than an amount of the treating agent that is applied to the third section when the remaining amount is not less than the second amount, and wherein the plurality of specific image portions includes a high-priority specific image portion corresponding to a priority higher than a predetermined priority and a low-priority specific image portion other than the high-priority specific image portion, the low-priority image portion being formed in the third section of the recording medium.
