Image forming apparatus to have processing apparatus and processing method of image forming apparatus

A processing method for an image forming apparatus to have a processing apparatus, comprising:

• receiving an input of a processing condition;
• comparing a printing coverage of an image that is going to be printed with a reference printing coverage;
• estimating if the printing coverage of the image that is going to be printed is larger than the reference printing coverage a size or area of a processing region of a printing medium at which the inputted processing operation is to be performed;
• forming the image on the printing medium except the processing region;
• and
• performing the processing operation on the printing medium.

An image forming apparatus, comprising:

• a main developing apparatus to form a first image on a printing medium;
• an auxiliary developing apparatus to form an additional image on the printing medium;
• a processing apparatus to perform processing operations on the print medium;
• a processing region on the print medium in which to perform the processing operations;
• and
• a control portion to output a selecting signal if a mode is selected so that a user can determine whether to allow the control portion to form the additional image on the processing region.

A method of forming an image in an image forming apparatus, comprising:

• receiving an input of a processing condition to be processed on a printing medium;
• receiving an input of an image to be printed on a printing medium;
• comparing a size of a printing coverage of the image to be printed on the printing medium with a size of a reference printing coverage;
• and
• controlling the developing of the image on a processing region based on the result of the comparison between the size of the printing coverage and the size of the reference printing coverage.

A computer readable medium to contain computer-readable codes as a program to perform a method in an image forming apparatus to have a processing apparatus, the method comprising:

• receiving an input of a processing condition;
• comparing a printing coverage of an image that is going to be printed with a reference printing coverage;
• estimating if the printing coverage of the image that is going to be printed is larger than the reference printing coverage a size or area of a processing region of a printing medium at which the inputted processing operation is to be performed;
• forming the image on the printing medium except the processing region;
• and
• performing the processing operation on the printing medium.
