Image forming apparatus and method of controlling the same

An image forming apparatus that forms an image on a recording medium, comprising:

• an image information input section that inputs image information;
• an image forming section that forms an image on a recording medium based on the input image information inputted by said image information input section;
• an operating state processing section that executes an operating state transferring process that causes said image forming section to transfer from a stopped state to an operating state and a stopped state transferring process that causes said image forming section to transfer from the operating state to the stopped state;
• and
• a control section that controls whether the stopped state transferring process is to be executed by said operating state processing section in a case where said image forming section is in the operating state and an error that makes image formation by the image forming apparatus impossible has occurred.
