Abstract
An image forming apparatus and an image forming method constituted as follows can suppress a mix color phenomenon and the like without consuming a large amount of pre-ejected ink. A cap for attaching to/detaching from a liquid eject portion of the recording head is arranged. The recording head ejects liquid while the cap is moving from an attached state to the liquid eject portion to a detached state. Alternatively, a recording head for recording, the cap for capping a liquid eject portion of the recording head and a pump for sucking via the cap may be arranged. The recording head ejects liquid while the cap is moving from an attached state to the liquid eject portion to a detached state, after a sucking operation by the pump is executed.
