Abstract: An image forming apparatus includes a transfer drum for superimposing different color toner images to create a multicolor iamge. The images are formed on an image member which is supplied to the apparatus in a cartridge. The cartridge is loaded in the apparatus by a first movement generally parallel to the axes of rotation of the transfer drum and the image member to a position in which the image member is spaced from and opposing the transfer drum. The cartridge is then rotated around one of its corners to move the image member into transfer engagement with the transfer drum.

Abstract: An image forming apparatus is supplied with an image member contained in a replaceable cartridge. The image forming apparatus includes a fuser requiring offset preventing liquid. The image member cartridge includes a source of offset preventing liquid accessible to the fuser.

Abstract: An image-forming apparatus, for example, electrophotographic printer has a replaceable cartridge which includes an image member, for example, a rotatable photoconductive drum. The drum cooperates with a transfer member, for example, a transfer drum which transfer member must be cleaned. The cartridge includes a chamber for receiving toner cleaned from the transfer member. Preferably, the image-forming apparatus creates a series of color toner images which are transferred to the surface of the transfer member in registration to create a multicolor image. The multicolor image is transferred in turn to a receiving sheet. The residual toner on the transfer member can be cleaned either by a cleaning device permanently located in the apparatus or a cleaning device in the cartridge. In either instance, the toner is collected in the cartidge and therefore does not require separate maintenance beyond replacement of the cartridge.
