An image forming system includes an image forming unit, a pressure-bonding processing unit, a display portion, and a control unit capable of controlling the image forming unit by acquiring image data for forming a toner image on a recording medium in an operation in an image forming mode. The control portion controls the display portion to issue a warning in a case that the toner image to be formed on an inner surface of the recording medium to be folded protrudes outside a film region, the film region being a region of the inner surface to which a thermosensitive adhesive film is to be supplied.

Image forming system

An image forming apparatus includes a photosensitive member; a charging member configured to electrically charge the photosensitive member; a developing device configured to form a toner image by supplying toner to the photosensitive member; a transfer member configured to transfer the toner image from the photosensitive member onto a toner image receiving member; a cleaning member provided in contact with the photosensitive member and configured to remove the toner remaining on a surface of the photosensitive member after transfer; and a controller configured to carry out a process for notifying information on a lifetime of the charging member, on the basis of use amount information on a use amount of the charging member and contact pressure information on contact pressure applied by the cleaning member to the photosensitive member.

Image forming apparatus

An image forming apparatus includes an image bearing member, a toner image forming portion, a transfer member, a cleaning member, and a controller configured to carry out a process for notifying information on a lifetime of the image bearing member on the basis of information on contact pressure of the cleaning member to the image bearing member.

An image forming apparatus includes an image bearing member, a transfer member, a cleaning blade, an information storing member configured to store information on contact pressures of the cleaning blade to the image bearing member, an information input portion, and an executing portion configured to execute a toner supplying operation for supplying toner to the cleaning portion using a toner image formed on the image bearing member, in a period other than a period in which the toner image is formed on the image bearing member, for each predetermined number of image forming operations. On the basis of the information inputted to the input portion, the executing portion sets amounts of the toner supplied to the respective regions in the toner supplying operation.

Image forming apparatus with storage of cleaning blade contact pressure

An image forming apparatus includes an image bearing member, a transfer member, a cleaning member, and an executing portion configured to execute a supplying operation for forming a predetermined toner image on the image bearing member during non-image formation and then supplying toner of the predetermined toner image to the contact portion. The executing portion executes the supplying operation with a forming condition of the predetermined toner image preset on the basis of information preset on contact pressure applied by the cleaning member to the image bearing member.
