Abstract

An image forming apparatus and an image forming system, the image forming apparatus including a memory to store first side position and second side position detected by a side end detector, a correction mechanism to movably support at least a registration roller of a first sheet conveyor and a second sheet conveyor in a direction perpendicular to a sheet conveying direction, and a controller to calculate a deviation between the first side position and the second side position, and to set the deviation as a correction amount of the correction mechanism.

First claim

What is claimed is:

1. An image forming apparatus comprising:
a sheet feeder, including a roller, to feed a sheet to a sheet conveyance passage;
an image former, including a transfer belt, to form an image on the sheet;
a first sheet conveyor, including a registration roller, at an upstream side of an image forming position in which the image former forms the image on the sheet, to convey the sheet along a sheet conveying direction;
a sheet reverser, including a guiding roll…
