IMAGE FORMING APPARATUS
First Claim
1. An image forming apparatus comprising:
- a first conveyor that conveys a print medium;
a cutter that cuts the print medium conveyed by the first conveyor;
a second conveyor that conveys, in a first direction, the print medium cut by the cutter;
a detection image forming section that forms a detection image on each of the print medium cut by the cutter and the second conveyor;
a detector that detects, at two positions that are in a second direction, one of the detection image formed on the print medium cut by the cutter and the detection image formed on the second conveyor, the second direction being substantially orthogonal to the first direction; and
a controller that varies one or both of a conveying speed of the print medium to be conveyed by the first conveyor and a cutting speed of the print medium to be cut by the cutter, on a basis of a comparison of the detection image detected at the two positions by the detector.

Abstract
An image forming apparatus includes a first conveyor, a cutter, a second conveyor, a detection image forming section, a detector, and a controller. The first conveyor conveys a print medium. The cutter cuts the conveyed print medium. The second conveyor conveys, in a first direction, the print medium cut by the cutter. The detection image forming section forms a detection image on the print medium and the second conveyor. The detector detects, at two positions in a second direction, the detection image formed on the print medium or the detection image formed on the second conveyor. The controller varies one or both of a conveying speed of the print medium to be conveyed by the first conveyor and a cutting speed of the print medium to be cut by the cutter, on the basis of a comparison of the detection image detected at the two positions.
