Image Forming Apparatus, Control Method and Non-Transitory Computer-Readable Medium

摘要

An image forming apparatus includes an image forming device for forming a pattern image having unit images on a photosensitive member, a sensor for irradiating the pattern image with light and detecting reflected light, and a controller for controlling the image forming device to form a pattern image for printing used when printing and a pattern image for detection to be detected by the sensor on the photosensitive member. A first pattern image for printing includes a predetermined number of first unit images arranged with being spaced from each other, each of the first unit images being smaller than a predetermined size. A first pattern image for detection corresponding to the first pattern image for printing includes more than the predetermined number of the first unit images arranged with being spaced from each other.

1. An image forming apparatus comprising:
an image forming device configured to form a pattern image, in which unit images are arranged, on a photosensitive member; a sensor configured to irradiate the pattern image with light and to detect reflected light; and a controller configured to control the image forming device to form a pattern image for printing and a pattern image for detection on the photosensitive member, the pattern image for printing being to be used when printing, and the pattern image for detection being to be detected by the sensor, wherein a first pattern image for printing comprises a predetermined number of first unit images, the first unit images being arranged with being spaced from each other per a predetermined area, each of the first unit images being smaller than a predetermined size, and wherein a first pattern image for detection, which corresponds to the first pattern image for printing, comprises more than the predetermined number of the first unit images, the first unit images being arranged with being spaced from each other per the predetermined area.
