There is an image processing apparatus which can perform the character processing works of character string on a display screen such as a CRT. This apparatus has: a keyboard having a special function input section to input a special code and a normal character input section to input normal code information different from the special code; a first memory to continuously store, as addresses, the special code inputted by the keyboard to display information on the basis of the codes stored in the first memory; a second memory to store the positional information regarding the special code; and a controller to control the display for allowing predetermined information to be displayed on the display on the basis of the special code stored in the first memory. The above special code may include either of carriage return code, tab code, centering code, gathering code, and space code. With this apparatus, the input and edit proceedings of new characters can be easily executed at any positions on the CRT by use of a buffer memory of a small capacity, so that the use efficiency of the memory is improved.
