    摘要： 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.

    摘要： A developing device includes: a housing in which a developer is contained; a cover member configured to cover an upper opening of the housing; a developer holder that is supported by the housing and holds the developer on an outer surface and rotates; a regulating member that faces the developer holder and configured to regulate an amount of the developer on the outer surface; a first exit path inclined toward an inside of the housing and configured to exit air from the inside of the housing to an outside of the cover member; and a second exit path that connects the first exit path and a filter member provided on the cover member, the filter member preventing passage of the developer and allowing passage of the air.

    摘要： An image forming apparatus includes an image forming unit, a fixing unit, a heating portion and a removal unit to remove a particulate dust generated due to vaporization of a parting agent by heat in the fixing unit. The removal unit includes a sheet-like filter provided with a base layer and a collecting layer laminated on the base layer for collecting dust. The removal unit includes a holding unit to hold the filer in a cylindrical shape with the base layer outside and the collecting layer inside. The removal unit includes a fan connected to one of opening end sides of the filter held in the cylindrical shape and generates an air flow inside of the cylindrical shape which causes an air passing from outside of the filter to inside to flow toward the one of opening end sides.
