An image-forming apparatus includes a condensation determiner that determines whether there is a possibility of condensation occurring inside the image-forming apparatus using condensation determination information including a measured apparatus temperature inside the apparatus, a preparation processor that performs a preparation process for executing a print function, and a preparation waiting time setter that sets a preparation waiting time indicating a period of time for performing the preparation process. When the image-forming apparatus is powered and it is determined that there is a possibility of condensation occurring inside the image-forming apparatus, a preparation waiting time is set using the condensation determination information and the preparation process is started. After counting of the preparation waiting time is started, it is determined that a periodically-measured fusing temperature reached a predetermined target temperature, and thereafter, the counted preparation waiting time elapsed, the preparation process is canceled.
