Mitosis is one part of a cell cycle; the others are G1, S and G2 in that order.  In the first stage (G1) cell growth occurs and the proteins and organelles necessary for cell division are produced.  During the S phase, the DNA is copied within the nucleus (the nuclear membrane does not break down).  Then in the G2 phase the remaining changes needed for cell division occur.  The the cell enters mitosis.  In prophase, the nuclear membrane breaks down, in metaphase the chromatids (two copies of DNA made in S phase) line up on the cell equator, in anaphase the chromatids are pulled apart by the spindle fibres to opposite sides of the cell, and in telophase the two new nuclear membranes are formed.  Only then does cell division occur, and it is called cytokinesis (not mitosis).  So, mitosis is only one stage in cell division, which can be considered a form of asexual reproduction.  Commonly, though technically incorrect, the entire process is referred to as mitosis.

Mitosis is a form of reproduction because it does produce more cells. But it does not provide genetic variation which is meiosis also known as sexual reproduction. mitosis is a type of sexual reproduction called asexual reproduction.Within this it undergoes the cell cycle which is what makes it produce more cells. Even though the cells are identical, it still counts as a form of reproduction

Mitosis is a form of asexual reproduction. Mitosis is the process by which cells make exact copies of themselves. Simple organisms such as prokaryotes merely make a copy of themselves and split. It may also be referred to as binary fission.
