Abstract:
An image forming apparatus in which a cartridge is detachably attachable, the cartridge having at least a toner containing part and a memory in which predetermined information is stored, comprising:an image bearing member; an image forming part for forming a toner image on said image bearing member; a detector for detecting the density of the toner image on said image bearing member; a transferring part for transferring an image to be recorded onto a transferring material on said image bearing member directly or indirectly to the transferring material; a density adjusting control part for forming a predetermined pattern on said image bearing member, executing a detection of the density of the predetermined pattern with said detector, and determining an image forming condition according to a result of the detection of the density of the predetermined pattern; and an image recording control part for forming an image to be recorded onto the transferring material under the image forming condition determined by said density adjusting control part, wherein, in the case that the image is to be recorded onto the transferring material, the density adjusting control part determines the image forming condition such that an image density on said image bearing member is varied depending on the predetermined information stored in the memory of the cartridge.
