Claim Text:
1. A conveyor device for mounting on an image forming apparatus, the image forming apparatus including an image forming section for forming an image on a sheet, the conveyor device having: a first conveyance path through which a sheet is conveyed after an image is formed on a side of the sheet by the image forming section; a reverse conveyance path branched from the first conveyance path; and a second conveyance path branched from the reverse conveyance path and through which the sheet is conveyed back to the image forming section, and the conveyor device comprising: a reversing section disposed on the reverse conveyance path; a decurling section spaced apart from the reversing section on the reverse conveyance path; and a controller configured to control the reversing section, wherein in a situation in which the sheet is not conveyed to the reversing section, the sheet is ejected onto an exit tray without passing through the decurling section and the reversing section, the controller controls the reversing section based on a parameter so as to adjust either or both of: the parameter is at least one from among an amount of curl of the sheet, a material of the sheet, a size of the sheet, a thickness of the sheet, an image density of the image formed on the sheet, a temperature, and a humidity, the reversing section reverses a conveyance direction of the sheet that is fed into the reverse conveyance path so as to feed the sheet into the second conveyance path, the decurling section applies decurling by urging the sheet in a direction of forming a convex curl with a side opposite to the image-formed side facing outward, the controller controls the reversing section based on the parameter so as to adjust acceleration time indicating a time period taken for changing a conveyance speed of the sheet from a first minimum speed to a first conveyance speed, the first minimum speed is a minimum speed at which the sheet is fed from the reverse conveyance path into the second conveyance path, and the first conveyance speed indicates a speed at which the sheet is conveyed in the second conveyance path.
