1. A powder application apparatus comprising:
a driver configured to move a member in a predetermined direction;
a powder supplier configured to supply powder onto a surface of the member;
a squeegee positioned at a distance from the member, the squeegee being configured to adjust a thickness of the powder supplied onto the surface of the member by the powder supplier; and
an ultra-high frequency vibration generator connected to the squeegee,
wherein:
the ultra-high frequency vibration generator is configured to make the squeegee vibrate at a frequency of 2 kHz or more and 300 kHz or less;
the squeegee has a columnar shape having an axis parallel to the surface of the member and orthogonal to a moving direction of the surface of the member; and
the ultra-high frequency vibration generator is configured to make the squeegee vibrate in a horizontal direction which is both parallel to a main surface of the squeegee and substantially parallel to the axis of the squeegee and in a perpendicular direction which is perpendicular to the main surface of the squeegee such that a magnitude of vibration in the horizontal direction is larger than a magnitude of vibration in the perpendicular direction.
