Abstract: Embodiments of the present disclosure provide an image forming control method, a consumable chip, an image forming apparatus, and a consumable. For the image forming control method, based on the environmental data, the encryption and decryption processing and transmission are performed on the preset compensation value of the image forming control parameter using the environmental data respectively detected by the consumable chip and the image forming apparatus. The preset compensation value is prevented from being intercepted and tampered during transmission, which makes data transmission more secure, thereby ensuring the printing and image forming quality.
