Abstract
According to an embodiment, an image forming apparatus executes, if an execution frequency setting of positional deviation correction in setting information is equal to or larger than a reference value, the positional deviation correction by using an image pattern for positional deviation measurement that is formed to be equal to or larger than one cycle of a transfer belt. Further, the image forming apparatus executes, if the execution frequency setting of the positional deviation correction in the setting information is less than the reference value, the positional deviation correction by using an image pattern for positional deviation measurement that is formed to be smaller than one cycle of the transfer belt.
Claims10
An image forming apparatus, comprising:
- an exposure device that forms an electrostatic latent image;
- a transfer belt that includes an endless belt supported by a roller, a toner image being transferred to the transfer belt, the toner image being obtained by developing, with toner, the electrostatic latent image formed by the exposure device;
- a memory that stores setting information related to positional deviation correction for correcting a deviation of an exposure position in the exposure device;
- and
- a processor configured to
- execute, if an execution frequency setting of the positional deviation correction in the setting information is equal to or larger than a predetermined value, the positional deviation correction by using an image pattern for positional deviation measurement that is formed to be equal to or larger than one cycle of the transfer belt, and
- execute, if the execution frequency setting of the positional deviation correction in the setting information is less than the predetermined value, the positional deviation correction by using an image pattern for positional deviation measurement that is formed to be smaller than the one cycle of the transfer belt.
