Abstract:
An image forming apparatus includes a latent image bearer, a latent image writing device, a developing device, a conveyance unit to convey a recording medium, a transfer device, a length data acquisition unit to obtain a length of the recording medium in a conveyance direction of the recording medium, an image forming processor to form a test pattern, and a light quantity correction calculator that acquires image density data of the test pattern and calculates a light quantity correction value to correct a light quantity. The image forming processor sets a position of the test pattern on the recording medium in the conveyance direction of the recording medium and a length of the test pattern in the conveyance direction of the recording medium based on the length of the recording medium in the conveyance direction of the recording medium obtained by the length data acquisition unit.

Claim (Index 3):
The image forming apparatus according to  claim 2 ,\n wherein the light quantity correction calculator corrects the light quantity with which the latent image writing device exposes the surface of the latent image bearer based on a first light quantity correction value corresponding to a characteristic of the latent image writing device, calculates a second light quantity correction value based on the image density data of the test pattern formed on the recording medium using the first light quantity correction value, and calculates the light quantity correction value based on the first light quantity correction value and the second light quantity correction value.
