摘要： A hot-melt type ink jet printer includes a nozzle head for ejecting a hot-melt type ink onto a sheet. The printer has a sheet feed passage defined by, in order from an upstream side in a sheet feeding direction, a sheet supply roller, a preheat platen, a sheet feed roller, a main platen, a cooling platen, discharge roller and a sheet discharge opening. The preheat platen and main platen have preheater and main heater, respectively, and these platen and the cooling platen are supported on a frame. A first suction port is formed between the main platen and the cooling platen and a second suction port is formed between the cooling platen and the frame. A power board and a cooling fan is provided within the frame for cooling the power board. By rotation of the cooling fan, air is introduced from the sheet discharge opening into the frame through the first and second suction ports to also cool the cooling platen and the heating platen.

摘要： Image forming apparatuses include: a casing; an image forming unit removable from the casing in a first direction; and plural developer cartridges. The cartridges may be attached and detached with respect to the image forming unit in a second direction that is inclined toward the first direction. Other image forming apparatuses include: a casing; an exposure device; a plurality of cartridges configured to be attached and detached with respect to the casing in a first direction; and a recording medium transport system for transporting recording media adjacent the photosensitive members in a second direction. The first direction may be inclined with respect to the second direction, and at least a portion of optical paths of the light emitted from the exposure device may extend parallel with the first direction. Aspects also relate to image forming units, e.g., for use in image forming apparatuses as described above.

摘要： A developing cartridge that maintains a pressing condition to press a developer carrier against the image carrier is described. The developing cartridge may include a coil spring that presses the developer carrier against the image carrier. The coil spring may include a handle that transmits a pressing force to the coil spring via the contacting member. By doing so, every time the developing cartridge is replaced, a new coil spring and handle can be provided for the color laser printer with the developing cartridge attached. Therefore, a constant pressure by the coil spring can be continuously maintained. Thus, a preferable pressure condition of the developer carrier against the image carrier can be continuously maintained.

摘要： A first cartridge and a second cartridge are detachably mounted in a housing of the image-forming device. The first cartridge is formed thicker than the second cartridge in a thickness direction orthogonal to a mounting direction of the first and second cartridges. The housing has a cartridge-accommodating section that accommodates the first and second cartridges. The cartridge-accommodating section includes first and second accommodating sections that are disposed continuously along the mounting direction and that are partly displaced with respect to each other in the thickness direction. The second accommodating section is disposed upstream of the first accommodating section with respect to the mounting direction and is formed thicker than the first cartridge and thinner than both the first and second cartridges together when the first and second cartridges are accommodated in the cartridge-accommodating section. The first accommodating section is formed thicker than the first and second cartridges together when the first and second cartridges are accommodated in the cartridge-accommodating section.
