TREATMENT-LIQUID APPLICATION APPARATUS AND IMAGE FORMING SYSTEM INCORPORATING SAME |
摘要 |
A treatment-liquid application apparatus includes a rotary treatment-liquid applicator, a rotary treatment-liquid supplier, a transfer rotator, and a contact load adjuster. The contact load adjuster adjusts a contact load of the rotary treatment-liquid supplier on the treatment-liquid applicator. After feeding of a recording medium is initiated by contact between the treatment-liquid applicator and the transfer rotator, an acceleration time until a feed speed of the recording medium reaches a constant speed during printing is set. Before feeding of the recording medium is initiated, the rotary treatment-liquid supplier contacts the treatment-liquid applicator and imparts a contact load L0. During an acceleration operation of the recording medium after feeding of the recording medium is initiated, the transfer rotator contacts the treatment-liquid applicator via the recording medium and imparts a contact load L1, and the contact load adjuster adjusts the contact load L1 to be greater than the contact load L0. |

1. A treatment-liquid application apparatus, comprising:
a rotary treatment-liquid applicator disposed on a feed path of a long recording medium to apply a treatment liquid measured to the recording medium; a rotary treatment-liquid supplier disposed below the rotary treatment-liquid applicator to contact and retract from the rotary treatment-liquid applicator, scoop up the treatment liquid, and supply the treatment liquid to the rotary treatment-liquid applicator; a transfer rotator disposed above the rotary treatment-liquid applicator to contact and retract from the rotary treatment-liquid applicator via the recording medium and transfer the treatment liquid measured on the rotary treatment-liquid applicator to the recording medium in contact with the rotary treatment-liquid applicator; and a contact load adjuster to adjust a contact load of the rotary treatment-liquid supplier on the rotary treatment-liquid applicator, wherein, after feeding of the recording medium is initiated by contact between the rotary treatment-liquid applicator and the transfer rotator, an acceleration time until a feed speed of the recording medium reaches a constant speed during printing is set, wherein, before feeding of the recording medium is initiated, the rotary treatment-liquid supplier contacts the rotary treatment-liquid applicator and imparts a contact load L0, and wherein during an acceleration operation of the recording medium after feeding of the recording medium is initiated, the transfer rotator contacts the rotary treatment-liquid applicator via the recording medium and imparts a contact load L1, and the contact load adjuster adjusts the contact load L1 to be greater than the contact load L0. |
