A maintenance support system includes an image forming apparatus, a management device, and an information processing terminal. The image forming apparatus generates data including terminal identification information identifying the terminal and sends it to the management device. The management device includes: an issuing processor that, upon receiving the data, issues receipt identification information and sends it to the image forming apparatus or terminal; a memory that stores the terminal identification information in the data and the receipt identification information; and a processor that, upon receiving the terminal identification information and receipt identification information from the terminal, compares the received terminal identification information and receipt identification information with the terminal identification information and receipt identification information stored in the memory, and outputs a result of the comparison. The terminal receives the receipt identification information, and sends the received receipt identification information and the terminal identification information.
