Image forming apparatus with setting unit for setting current values for motor

摘要

An image forming apparatus including an electrophotographic process is disclosed. The image forming apparatus detects a load angle of a motor associated with conveying of an n-th sheet. In accordance with the detected load angle, current values for motors associated with conveying of the n-th sheet, a current value for a motor associated with feeding of sheets following the n-th sheet, and a current value for a motor associated with conveying of the sheets following the n-th sheet are set. Such control is executed when power is turned ON or the like.

主权项

1. An image forming apparatus for forming an image on a sheet material comprising:
a conveying unit having a plurality of conveying paths to convey the sheet material; a plurality of first motors configured to drive a plurality of first rollers, each of which is disposed on a respective conveying path of the plurality of conveying paths; a second motor configured to drive a second roller disposed downstream of a merging point of the plurality of conveying paths; a detection unit configured to detect a load angle of the second motor; a third motor configured to drive a third roller disposed downstream of the second roller; and a setting unit configured to set, in accordance with the load angle of the second motor detected by the detection unit at a time of conveying an n-th sheet material, where n is a natural number equal to or larger than 1, current values for the plurality of first motors and the second motor at a time of conveying sheet material following the n-th sheet material, wherein, in accordance with the load angle of the second motor detected by the detection unit at the time of conveying the n-th sheet material, the setting unit sets a current value for the third motor at the time of conveying the n-th sheet material.
