Abstract
An image forming apparatus includes an image bearing member, a cleaning device detachably provided on a main assembly to clean toner remaining on the image bearing member, a main assembly feeding portion detachably provided on the main assembly to feed the toner discharged from the cleaning device, a collecting container detachably provided on the main assembly to collect the toner discharged from the main assembly feeding portion, a control portion, and an operating portion capable of inputting a predetermined instruction to the operating portion. Without an image forming operation based on the predetermined instruction, the control portion performs a discharging operation in which the main assembly feeding portion is caused to be driven to discharge the toner inside of the main assembly feeding portion.
Claims10
An image forming apparatus comprising:
- an image bearing member;
- a cleaning device detachably provided on a main assembly and configured to clean toner remaining on the image bearing member;
- a main assembly feeding portion provided on the main assembly and configured to feed the toner discharged from the cleaning device;
- a collecting container detachably provided on the main assembly and configured to collect the toner discharged from the main assembly feeding portion;
- a control portion configured to control the main assembly feeding portion;
- and
- an operating portion capable of inputting a predetermined instruction to the operating portion,
- wherein without an image forming operation based on the predetermined instruction, the control portion performs a discharging operation in which the main assembly feeding portion is caused to be driven to discharge the toner inside of the main assembly feeding portion.
An image forming apparatus comprising:
- a bottle detachably provided on a main assembly and configured to accommodate tone;
- a hopper provided on the main assembly and configured to accommodate the toner replenished from the bottle;
- a developing device detachably provided on the main assembly and configured to accommodate the toner replenished from the hopper and develop a latent image formed on an image bearing member, the developing device being capable of discharging an excessive toner which becomes excessive in the developing device with a replenishing operation by the hopper;
- a control portion configured to control the hopper and the bottle;
- and
- an operating portion capable of inputting a predetermined instruction to the operating portion,
- wherein without an image forming operation based on the predetermined instruction, the control portion performs a discharging operation in which the toner inside of the hopper is discharged and the toner is discharged from the developing device by driving the developing device in a state in which toner replenishment from the bottle to the hopper is stopped.
