An image forming apparatus comprising: an image bearing member configured to bear a toner image; a transfer member configured to transfer the toner image from said image bearing member onto a toner image receiving member at a transfer portion; a cleaning blade contacting said image bearing member at a cleaning portion and configured to remove a deposited matter on said image bearing member with movement of said image bearing member; an information storing member configured to store information on contact pressures which were measured by a measuring apparatus in advance, the contact pressures being corresponding to contact forces per unit length of said cleaning blade to said image bearing member with respect to a widthwise direction perpendicular to a movement direction of said image bearing member in each of a plurality of regions of said cleaning blade with respect to the widthwise direction; an input portion to which the information stored in said information storing member is inputted; and an executing portion configured to execute a toner supplying operation for supplying toner to the cleaning portion using a toner image formed on said image bearing member, in a period other than a period in which the toner image is formed on said image bearing member, for each predetermined number of image forming operations, wherein on the basis of the information inputted to said input portion, said executing portion sets amounts of the toner supplied to the respective regions in the toner supplying operation, wherein said executing portion sets the amounts of the toners supplied to the respective regions in the toner supplying operation so that the amount of the toner supplied to the region in which the contact pressure is a first contact pressure is smaller than the amount of the toner supplied to the region in which the contact pressure is a second contact pressure larger than the first contact pressure. an image bearing member configured to bear a toner image; a transfer member configured to transfer the toner image from said image bearing member onto a toner image receiving member at a transfer portion; a cleaning blade contacting said image bearing member at a cleaning portion and configured to remove a deposited matter on said image bearing member with movement of said image bearing member; an information storing member configured to store information on contact pressures which were measured by a measuring apparatus in advance, the contact pressures being corresponding to contact forces per unit length of said cleaning blade to said image bearing member with respect to a widthwise direction perpendicular to a movement direction of said image bearing member in each of a plurality of regions of said cleaning blade with respect to the widthwise direction; an input portion to which the information stored in said information storing member is inputted; and an executing portion configured to execute a toner supplying operation for supplying toner to the cleaning portion using a toner image formed on said image bearing member, in a period other than a period in which the toner image is formed on said image bearing member, for each predetermined number of image forming operations, wherein on the basis of the information inputted to said input portion, said executing portion sets amounts of the toner supplied to the respective regions in the toner supplying operation, wherein said executing portion sets the amounts of the toners supplied to the respective regions in the toner supplying operation so that the amount of the toner supplied to the region in which the contact pressure is a first contact pressure is smaller than the amount of the toner supplied to the region in which the contact pressure is a second contact pressure larger than the first contact pressure.
