In a RAM are stored a first deflection information table representing the relationship between the rotation amount and the deflection amount of a photosensitive element, a second deflection information table representing the relationship between the rotation amount and the deflection amount of a developing sleeve, a writing sensitivity information table representing the relationship between the rotation amount of the photosensitive element and latent image writing sensitivity, and an image forming condition information table representing the relationship between the rotation amount and laser power. An information input unit is provided to input the respective tables. During a print job, laser power is changed on the basis of the image forming condition information table, and laser power which causes deviation in an opposing direction is calculated on the basis of information input in a standby state to update the image forming condition information table. |
