Abstract: In an ink-jet recording apparatus having two recording modes having different resolutions in recording, high density is realized in each of the recording modes in an excellent state. In a high-resolution recording mode, a colorless processing liquid to cause ink and its color material to be insoluble or to agglomerate is discharged, and the processing liquid and the ink are mixed on a recording medium. Thus, the ink becomes insoluble and therefore does not penetrate deeply into the recording medium, so that dots formed by the ink have a smaller diameter. As a result, high-resolution recording with the small-diameter dots can be realized. In a low-resolution recording mode, the diameter of dots formed by the ink without using the processing liquid is larger than in the foregoing case. Accordingly, dots can be densely arranged in the two modes, so that high density can be realized in an excellent state.

Abstract: The present invention provides a recording apparatus in which a recording medium is conveyed by a driven rotary member and a convey rotary member urged against the driven rotary member by a biasing means supported by a rockable support member, so that an image is recorded on the recording medium contacted with the driven rotary member by a recording means disposed at a downstream side of the convey rotary member. Wherein, when the convey rotary member is rotated in the recording medium conveying direction, the support member is shifted toward a direction for urging the convey rotary against the driven rotary member, by a rotational force of a rotation drive transmitting member of the convey rotary member, so that convey accuracy of the recording medium is improved and the good recording is performed.
