## Abstract

The image forming apparatus includes a paper feed unit that stores print paper used for printing, a paper size sensor that detects a paper size of the print paper stored in the paper feed unit, a filter information setting unit that sets filter information indicating the paper size detected by the paper size sensor in association with the paper feed unit, and a paper catalog list generating unit that extracts a paper catalog matching the filter information from paper catalogs included in predetermined paper catalog data and generates a paper catalog list using the extracted paper catalog.

## Claims

### Claim 1

An image forming apparatus comprising:
a paper feed unit to store print sheets of paper to be used for printing;
a paper size sensor that detects a paper size of the print paper stored in the paper feed unit;
a filter information setting unit to set filter information indicating the paper size detected by the paper size sensor in association with the paper feed unit; and
a paper catalog list generating unit to extract a paper catalog matching the filter information from paper catalogs included in predetermined paper catalog data and generates a paper catalog list using the extracted paper catalog.

### Claim 2 (depends on 1)

The image forming apparatus according to claim 1,
wherein the filter information setting unit determines whether the paper size detected by the paper size sensor is a predetermined standard size, sets the filter information in association with the paper feed unit when the paper size detected by the paper size sensor is the predetermined standard size, and does not set the filter information in association with the paper feed unit when the paper size detected by the paper size sensor is not the predetermined standard size.

### Claim 3 (depends on 1)

The image forming apparatus according to claim 1,
further comprising an opening/closing sensor to detect opening/closing of the paper feed unit and a paper feed setting unit to set a paper catalog associated with the paper feed unit,
wherein the filter information setting unit sets filter information indicating the paper size detected by the paper size sensor in association with the paper feed unit when the opening/closing of the paper feed unit is detected by the opening/closing sensor,
the paper catalog list generating unit generates the paper catalog list when the opening/closing of the paper feed unit is detected by the opening/closing sensor, and
the paper feed setting unit sets a paper catalog selected by a user from the paper catalog list as a paper catalog associated with the paper feed unit when the opening/closing of the paper feed unit is detected by the opening/closing sensor.

### Claim 4 (depends on 1)

The image forming apparatus according to claim 1,
wherein the paper catalog list generating unit generates a paper catalog list in which the paper catalogs are arranged in an arrangement order based on a current count value of the number of prints for each paper type, and
the arrangement order is selected by a user from an ascending order and a descending order

### Claim 5 (depends on 1)

The image forming apparatus according to claim 1,
further comprising a paper catalog registration unit that registers a paper catalog designated by a user as a user paper catalog,
wherein the paper catalog list generating unit extracts a paper catalog that matches the filter information from the registered user paper catalogs and generates a paper catalog list using the extracted paper catalog.
