Treatment liquid application device and image forming apparatus

A treatment-liquid application device comprising:

• a treatment-liquid container to store a treatment liquid;
• a liquid supply unit to supply the treatment liquid from the treatment-liquid container;
• a liquid chamber unit to store the treatment liquid supplied from the treatment-liquid container;
• a treatment-liquid carrier having a carrying surface movable into and out from the treatment liquid stored in the liquid chamber unit to carry the treatment liquid;
• a transport unit to transport an application target to an application position;
• a treatment-liquid applicator to apply the treatment liquid transferred from the treatment-liquid carrier, to the application target at the application position;
• and
• a partition disposed in an area of the liquid chamber unit defined by an imaginary entry plane, an imaginary exit plane, the carrying surface, and a bottom face of the liquid chamber unit,
• the imaginary entry plane including an entry line at which the carrying surface of the treatment-liquid carrier enters the treatment liquid stored in the liquid chamber unit, the imaginary entry plane vertically extending from the entry line,
• the imaginary exit plane including an exit line at which the carrying surface of the treatment-liquid carrier exits from the treatment liquid stored in the liquid chamber unit, the imaginary exit plane vertically extending from the exit line,
• the partition extending in a longitudinal direction of the treatment-liquid carrier perpendicular to a moving direction of the carrying surface of the treatment-liquid carrier,
• the partition having an edge portion adjacent to the carrying surface of the treatment-liquid carrier.
