An image communicating apparatus comprises: a reader as an image input unit for inputting code data such as character code or the like; a converter for converting the input code data into image data; a transmitting circuit for transmitting the code data supplied from the reader or the image data converted by the converter; and a controller for judging the function of an apparatus of the communication partner side and a line state or a communicating condition, thereby selecting either one of a mode to transmit the code data and a mode to transmit the image data converted by the converter in accordance with the results of the judgment. When the code data is transmitted in an error retransmitting mode and error data remains due to a defective line state or communicating condition, the controller selects the mode to transmit the image data converted by the converter.
