A fusing device includes: an endless rotatable fusing belt; a nip forming member that is disposed on an inner circumferential surface of the fusing belt; a pressure roller that is in pressure contact with the nip forming member from an outer side of the fusing belt and forms a fusing nip area between the pressure roller and the fusing belt; and a heat source that is disposed inside the fusing belt and heats the fusing belt. The fusing device further includes a heat-conductive member that is disposed on a lateral side of an outer circumference of the fusing belt. The heat-conductive member extends over a width area in a rotation axis direction of the fusing belt.

An image forming apparatus of the present invention is an image forming apparatus into which a memory device is insertable and which performs a printing process on an image of image data stored in the memory device. The image forming apparatus includes a memory reading section for detecting insertion of the memory device into the image forming apparatus, and a display processing section for performing a notification process of warning of accidental ingestion of the memory device, when the memory reading section detects the insertion of the memory device. This makes it more surely possible to cause a user to give attention to accidental ingestion by young children.
