20080223290 | LIQUID APPLYING APPARATUS AND INK JET PRINTING APPARATUS - It is an object of the present invention to provide a liquid applying apparatus which can prevent an applying liquid from evaporating while an applying operation is at a stop and which can reliably prevent the liquid from leaking even when for example, the posture of the apparatus is tilted. Thus, according to the present invention, an abutting member of a holding member is abutted, under an urging force of a spring, against an applying surface of an applying roller. Thus, a liquid holding space is formed between the applying roller and a holding member to hold the applying liquid. The abutting member is annularly formed of a single member.
