Abstract
According to one embodiment, an image forming apparatus includes an electrically conductive and grounded frame, an image forming unit, a print head, a holder that supports the print head, an electrically conductive urging member for urging the print head toward the image forming unit, and an electrically conductive arm extending from the urging member and electrically connected to the urging member. The arm floats when the print head moves away from the image forming unit and is electrically connected to the frame when the print head approaches the image forming unit.
