Imaging lens and imaging apparatus

An imaging lens comprising, successively in order from a position closest to an object side to an image side:

• a first lens group that remains stationary with respect to an image plane during focusing;
• and
• a focus lens group that moves along an optical axis during focusing,
• wherein assuming that
• a maximum image height is Ymax,
• a focal length of the imaging lens in a state where an infinite distance object is in focus is f, and
• a sum of a back focal length in terms of an air-equivalent distance and a distance on the optical axis from a lens surface closest to the object side in the first lens group to a lens surface closest to the image side in the imaging lens in a state where the infinite distance object is in focus is TL,
• Conditional Expressions (1) and (2) are satisfied, which are represented by
• 0.1<Ymax/f<0.26 (1), and
• 0.4<TL/f<1.1 (2), and
• wherein the imaging lens consists of, in order from the object side to the image side, the first lens group, the focus lens group that has a negative refractive power as a whole, and a rear lens group that remains stationary with respect to the image plane during focusing, and
• assuming that a focal length of the rear lens group is fR, Conditional Expression (13) is satisfied, which is represented by
• −0.9<fR/f<−0.1 (13).
