Disclosed is a method of buffering image information in which stored data in a frame memory is readout, and the readout data is written onto a recording medium on a line-by-line basis at a writing speed m (m is an integer) times as large as the speed of the reading, the method comprising steps of: changing-over sides of two buffer memories one of which is assigned interchangeably to a reading side and the other to a writing side, each having capacity for a single record line on a recording medium; reading stored data corresponding to the single record line in size from the frame memory and writing the readout data to the writing side buffer memory at the same speed as the speed of reading the stored data from the frame memory; and reading m times repeatedly, during said step of writing, data having been stored immediately before in the reading side buffer memory and supplying the readout data to a writing unit at the same speed as speed of writing in the writing unit.
