  • Patent number: 10061249
    Abstract: In an image forming apparatus, an image forming unit forms a first image of a first color and a second image of a second color. An obtaining unit obtains information related to relative positions of a first measurement image, which is formed on an image carrier, of the first color and a second measurement image, which is formed on an image carrier, of the second color. A generation unit generates correlation data based on first information corresponding to a first image forming speed and second information corresponding to a second image forming speed. A controller, in a case where the image forming unit forms an image at the second image forming speed, corrects relative positions of the first image and the second image based on the first information in advance and the correlation data.

  • Patent number: 10025250
    Abstract: An image forming apparatus capable of performing color misregistration correction at image forming speeds while reducing downtime. Image forming units form images of different colors. The formed images are transferred to an intermediate transfer belt. A pattern sensor detects color misregistration amounts of color patterns formed on the intermediate transfer belt. A CPU causes the image forming units to form first color patterns at a first speed and the pattern sensor to detect first color misregistration amounts, and causes the former to form second color patterns at a second speed different from the first speed and the latter to detect second color misregistration amounts. The CPU determines third color misregistration amounts at a third speed based on the first and second color misregistration amounts. The third speed is different from the first and second speeds.

  • Patent number: 9927753
    Abstract: An image forming apparatus includes a feeder including a tray and a pickup member, a size determiner, a sheet type setter, and a controller. The tray stacks a sheet thereon, and the pickup member feeds a contacted sheet. The feeder switches between a first state where the pickup member and the stacked sheet are in contact and a second state where the pickup member and the stacked sheet are separate. The size determiner determines a stacked sheet size. The sheet type setter sets a stacked sheet type. Where the type of the set sheet is a first type, the feeder switches from the second state to the first state when the size of the sheet is determined. Where the type of the set sheet is a second type, the feeder refrains from switching from the second state to the first state even when the size of the sheet is determined.
