an ink jet recording method forms an ink jet image on a recording medium by serially moving an ink jet recording head having a plurality of ink discharge ports arranged in an array along a conveyance direction of the recording medium . the method includes the step of providing a platen having a planar section upstream in the conveyance direction and a slant section slanted downstream in the conveyance direction and in a direction parting from the ink discharge ports , opposed to an array of the ink discharge ports when the ink jet recording head serially moves . the method further includes the step of forming an ink jet image on the recording medium by ink discharge from the ink discharge ports when the ink jet recording head moves at least three times across a same area of the recording medium , a reverse side of which is supported by the platen .
