  • Patent number: 11036449
    Abstract: An image forming apparatus (100) includes a guaranteed area (RA), a receiving section (501), a second determination section (504), and an execution section (505). The receiving section (501) receives jobs (JB). When the receiving section (501) receives a first job (JB1), the second determination section (504) determines whether or not a first user (U1) who has input the first job (JB1) matches a second user (U2) who has input a second job (JB2) that is under execution using the guaranteed area (RA). When the second determination section (504) determines that the first user (U1) matches the second user (U2), the execution section (505) loads an image included in the first job (JB1) into the guaranteed area (RA), and executes the first job (JB1) subsequent to the second job (JB2).
