    摘要： A disclosed image forming apparatus includes a recording head configured to eject liquid droplets onto a sheet to form an image; a transport unit configured to intermittently transport the sheet; a discharge transport unit disposed downstream the transport unit in a transport direction, the discharge transport unit including plural transport rollers configured to transport the sheet in a sheet discharge direction and plural spurs disposed facing the respective transport rollers and arranged in the transport direction; a guide member configured to hold the spurs and be rotatable about a most downstream side or a most upstream side in the transport direction to rotate in a direction away from a sheet transport path; and a stopping and holding unit configured to stop and hold the guide member in a position in which only the spur in the most downstream side in the transport direction is in contact with the sheet.

    摘要： An image forming apparatus includes a carriage carrying a recording head configured to discharge a droplet. A landing position error detecting pattern is formed on a pattern forming member. Based on a result of reading the landing position error detecting pattern, a landing position error of the droplet discharged by the recording head is corrected. Either a first pattern or a second pattern is selected as the landing position error detecting pattern, depending on a surface condition of the pattern forming member. The first pattern produces a relatively small amount of specular reflection compared with diffused reflection, while the second pattern produces a relatively large amount of specular reflection compared with diffused reflection, upon irradiation with light.
