Image forming apparatus

An image forming apparatus, comprising:

• a sheet support portion configured to support a sheet;
• an image forming portion configured to form an image on the sheet fed from the sheet support portion;
• a storage portion configured to store information concerning a sheet size which is inputted through an operation portion in associated with the sheet support portion;
• a notification portion configured to give notification;
• a size detection portion configured to detect a sheet size of the sheet supported by the sheet support portion;
• and
• a processor configured to execute one of a plurality of modes including a first mode and a second mode in a case where an image forming job is inputted, the first mode being a mode where the processor controls the image forming portion to form an image on the sheet only if a sheet size included in the image forming job is consistent with the sheet size stored in the storage portion, a second mode being a mode where the processor is capable of controlling the image forming portion to form the image on the sheet even if the sheet size included in the image forming job is inconsistent with the sheet size stored in the storage portion,
• wherein the processor controls, in the second mode, the image forming portion so as to form an image on the sheet in a case where the size detection portion detects one of regular sheet sizes and where the sheet size included in the image forming job is less than or equal to the sheet size detected by the size detection portion, and controls, in the second mode, the notification portion so as to give notification in a case where the size detection portion detects one of regular sheet sizes and where the sheet size included in the image forming job is larger than the sheet size detected by the size detection portion.

An image forming apparatus, comprising:

• a sheet support portion configured to support a sheet;
• an image forming portion configured to form an image on the sheet fed from the sheet support portion;
• a sheet conveyance portion configured to convey the sheet;
• a storage portion configured to store information concerning a sheet size which is inputted through an operation portion in associated with the sheet support portion;
• a size detection portion configured to detect a sheet size of the sheet supported by the sheet support portion;
• and
• a processor configured to execute one of a plurality of modes including a first mode and a second mode in a case where an image forming job is inputted, the first mode being a mode where the processor controls the image forming portion to form an image on the sheet only if a sheet size included in the image forming job is consistent with the sheet size stored in the storage portion, a second mode being a mode where the processor is capable of controlling the image forming portion to form the image on the sheet even if the sheet size included in the image forming job is inconsistent with the sheet size stored in the storage portion,
• wherein the processor controls, in the second mode, the image forming portion so as to form an image on the sheet in a case where the size detection portion detects one of regular sheet sizes and where the sheet size included in the image forming job is consistent with the sheet size detected by the size detection portion, and
• the processor controls, in the second mode, a conveyance operation by the sheet conveyance portion corresponding to the sheet size detected by the size detection portion and controls the image forming portion to form an image on the sheet in a case where the size detection portion detects one of regular sheet sizes and where the sheet size included in the image forming job is inconsistent with the sheet size detected by the size detection portion.
