US 10,459,389 B2 · Image forming apparatus

Abstract

Conventionally, it has been impossible to adjust a transportation direction magnification correspondingly to jobs, causing an image to be formed in an unintended size, while the transportation direction magnification for the image formed on the sheet varies with jobs. A controller included in an image forming apparatus selects an image adjustment chart used to adjust a transportation direction magnification that varies with job conditions of a job to be executed currently in a transportation direction of images transferred to sheets by a transferrer. The controller adjusts the transportation direction magnification for images formed by an image former based on the image adjustment chart formed on a sheet by the image former.

Dependent claims

An image forming apparatus comprising:

a transporter that transports a sheet;
an image former that forms an image;
a transferrer that is provided downstream of the image former along a transportation direction in which the transporter transports the sheet and transfers the image formed by the image former to the sheet;
and
a controller that selects an image adjustment chart used to adjust a transportation direction magnification for the image varying in the transportation direction and adjusts the transportation direction magnification for the image formed by the image former based on the image adjustment chart and a job condition of a job to be executed currently, the image adjustment chart being formed by the image former and transferred to the sheet by the transferrer.
