Abstract
A powder detector to detect an amount of powder in the powder container includes a wall without a through hole, a vibration plate attached to an inner face of the wall, a contact member to vibrate the vibration plate, and a vibration detector to detect a vibration state of the vibration plate. The vibration detector is attached to an outer face of the wall to face the vibration plate via the wall. The powder has flowability, and the vibration state of the vibration plate is affected by the powder in the powder container.
