PURPOSE:To shorten a transmission time when one station which processes high-density data transmits data to the opposite station which processes low density data by converting the density of transmit data according to the specified opposite station. CONSTITUTION:A document is edited on a CRT 60 firstly and then it is judged whether one-page edited information is divided into plural blocks r not. The 1st block is checked to judge whether the block consists of image data or character data. When the block consists of the image data, the opposite station scans a table map memory which contains terminal numbers and density data to make a decision between 8pel/mm and 16pel/mm. A table map is registered in the ROM of a PMEM 23 previously. When the data is transmitted at a rate of 8pel/mm, 1/2 density conversion is performed by a BMU 24 and an IMEM 25. Therefore, when one station processes high-density data and the opposite station processes low-density data, the amount of information to be transmitted decreases, so the speed of transmission to the opposite station is increased.
