Image forming apparatus using a cleaning device and cleaning method thereof

A cleaning device for an image forming apparatus comprising:

• a cleaning blade to remove waste developers remaining on one of a photosensitive medium and a transfer belt;
• and
• a cleaning member disposed on one side of the cleaning blade to remove the waste developers remaining on the cleaning blade;
• wherein the cleaning blade is disposed substantially below the photosensitive medium or the transfer belt while the cleaning blade is in contact with a surface of the photosensitive medium or the transfer belt.

An image forming apparatus, comprising:

• a main body;
• a scanning unit being disposed within the main body for generating an electrostatic latent image on a photosensitive medium;
• an image forming unit generating a visible image on the photosensitive medium by using a developer, and transferring the visible image to a piece of printing paper;
• and
• a cleaning device to remove waste developers remaining on the photosensitive medium, comprising:
• a first cleaning member to remove waste developers remaining on the photosensitive medium;
• a support bracket to support the first cleaning member;
• and
• a second cleaning member being disposed on one side of the first cleaning member to remove the waste developers remaining on the first cleaning member, wherein said second cleaning member comprises an absorption member.

An image forming apparatus, comprising:

• a main body;
• a scanning unit being disposed within the main body to generate an electrostatic latent image on a photosensitive medium;
• a developing unit generating a visible image on the photosensitive medium by using a developer;
• a transfer unit comprising a transfer belt to transfer the visible image on the photosensitive medium to a piece of printing paper;
• and
• a cleaning device to remove waste developers remaining on the transfer belt, comprising:
• a first cleaning member to remove waste developer remaining on the transfer belt;
• a support bracket to support the first cleaning member;
• a second cleaning member being disposed on one side of the first cleaning member to remove the waste developers remaining on the first cleaning member;
• and
• a compressing unit positioned to clean the second cleaning member.

A cleaning method of an image forming apparatus, comprising the steps of:

• a pre-cleaning step to pre-clean waste developers remaining on one of a transfer belt and a photosensitive medium prior to a first cleaning step;
• a first cleaning step to remove waste developers remaining on one of a transfer belt and a photosensitive medium of the image forming apparatus through the use of a cleaning blade;
• and
• a second cleaning step to clean waste developers remaining on the cleaning blade through the use of a cleaning member.
