1. A recording apparatus comprising:
a recording head having an ejection port surface and a step portion, wherein an ejection port configured to eject ink is arranged on the ejection port surface and the step portion (i) is at a position different from an area in which the ejection port is arranged on the ejection port surface side and (ii) is formed of at least one of a raised portion that is raised with respect to the ejection port surface or a recessed portion that is recessed with respect to the ejection port surface;
a wiper configured to wipe the ejection port surface; and
a moving unit configured to relatively move the wiper and the recording head so that the wiper moves with respect to the recording head in a first direction along the ejection port surface,
wherein, in a first wiping, the relative movement of the wiper and the recording head by the moving unit causes the wiper to pass in a vicinity of the step portion at a speed that is lower than a speed at which the wiper wipes the area in which the ejection port is arranged such that ink accumulated in the step portion is removed from the step portion, and
wherein, in a second wiping performed after the first wiping, the relative movement of the wiper and the recording head by the moving unit causes the wiper to be past the step portion of the recording head and wipe the recording head in the first direction toward the area in which the ejection port is arranged, and thereafter wipe the area in which the ejection port is arranged.
