Image forming apparatus, conveyance method, and non-transitory computer-readable recording medium storing program

A conveyance method in an image forming apparatus capable of printing on continuous sheet, the conveyance method comprising:

• conveying the continuous sheet by a fixing nip that fixes an image on an unfixed surface of the continuous sheet;
• conveying the continuous sheet by a downstream-side conveyance nip disposed on a downstream side of the fixing nip in a sheet conveyance direction;
• detecting a physical amount related to a thermal expansion state of a fixing member that forms the fixing nip;
• and
• controlling a driving aspect of at least one of a fixing section and/or a downstream-side conveyance section based on the detected physical amount related to the thermal expansion state, the fixing section being a fixing section in which the fixing nip is disposed, the downstream-side conveyance section being a downstream-side conveyance section in which the downstream side conveyance nip is disposed.

A non-transitory computer-readable recording medium storing a program, the program causing a computer of an image forming apparatus to execute predetermined processing, the image forming apparatus capable of printing on continuous sheet, wherein

• the predetermined processing includes:
• conveying the continuous sheet by a fixing nip that fixes an image on an unfixed surface of the continuous sheet;
• conveying the continuous sheet by a downstream-side conveyance nip disposed on a downstream side of the fixing nip in a sheet conveyance direction;
• detecting a physical amount related to a thermal expansion state of a fixing member that forms the fixing nip;
• and
• controlling a driving aspect of at least one of a fixing section, in which the fixing nip is disposed, and a downstream-side conveyance section, in which the downstream-side conveyance nip is disposed, based on the detected physical amount related to the thermal expansion state.
