An image formation apparatus and process cartridge exhibiting high
durability, in which such disadvantages as irregular recovery of
untransferred toner and the advance of carrier degradation are not
produced even when jointly using a trickle development system and a
cleanerless system, comprising an image support member on which a latent
image is formed; a developing unit that houses developer having carrier
and toner, develops the latent image formed on the image support member,
and recovers untransferred toner remaining on the image support member; a
carrier supply unit that supplies carrier to the developing unit; carrier
discharge means that discharges carrier housed in the developing unit to
outside of the developing unit; and lubricant supply means that supplies
lubricant onto the image support member.
