Classification: CPC G | IPC G

Claim 0:
1. An image forming apparatus comprising:
an image forming device including an image bearer to form a toner image on the image bearer;
a first transfer device including a first mover to transfer the toner image from the image bearer onto the first mover;
a second transfer device including a second mover to transfer the toner image from the first mover onto the second mover;
a transfer-pressure changer configured to change a transfer pressure of the second mover against the first mover;
an adhesion-amount detector configured to detect the toner image transferred onto the second mover and output a detection value indicating an amount of toner of the toner image adhering to the second mover; and
circuitry configured to
calculate a variable value for the amount of toner of the toner image adhering to the second mover based on the detection value and a target value of the amount of toner of the toner image to be transferred and adhere to the second mover, the variable value varying with a change in the transfer pressure,
reflect the calculated variable value in the detection value to correct the detection value,
adjust an image-forming condition based on the corrected detection value, and
set the image-forming condition of the toner image in the image forming device based on the corrected detection value.
