PURPOSE:To allow a communication while original size and recording size are different by adding a line end code which indicates a line end in a main scanning direction to every line when image information is stored as run length codes in an image memory. CONSTITUTION:When digital binary image information is inputted to a signal line (e), it is sample with a clock inputted from a signal line (a) and a change point detecting circuit 3 outputs a pulse when the image information varies in value from 0 to 1 or vice versa. This pulse is inputted to a run length calculating circuit 4, but this circuit initialize calculating operation every time the pulse appears on a signal line (c). A control circuit 2 latches the run length count result right before the initialization, i.e. the pulse appearing on the signal line (c) falls, and writes it in a memory 1. The control circuit 2 writes a line end code with a pulse from a line end detecting circuit 5 after writing the last run length in the memory 1.
