Image processing apparatus capable of performing printing with decoloring toner, method of controlling image processing apparatus, and storage medium

An image processing apparatus that is capable of performing image formation on recording sheets, by switchingly using decoloring toner and normal toner, comprising:

• a setting unit configured to set an upper limit of the number of prints on a user-by-user, for users registered in the image processing apparatus;
• a count unit configured to separately count the number of sheets printed with the decoloring toner and the number of sheets printed with the normal toner with respect to new sheets and reuse sheets, each used as the recording sheet, on a user-by-user basis;
• and
• a calculation unit configured to calculate a remaining printable sheets number by subtracting the number of printed new sheets and the number of printed reuse sheets, used for printing with the normal toner, from the upper limit of the number of prints and not to subtract the number of printed new sheets and the number of printed reuse sheets, used for printing with the decoloring toner, from the remaining printable sheets number.

An image processing apparatus that is capable of performing image formation on recording sheets, by switchingly using decoloring toner and normal toner, comprising:

• a count unit configured to count the number of sheets printed with the decoloring toner and the number of sheets printed with the normal toner, with respect to the recording sheets, on a user-by-user basis;
• an acquisition unit configured to acquire a decoloring toner use ratio of a logged-in user who has logged in the image processing apparatus, the decoloring toner use ratio indicating a ratio of the number of sheets printed with the decoloring toner to a total number of the number of sheets printed with the decoloring toner and the number of sheets printed with the normal toner, based on counts counted by the count unit;
• and
• a notification unit configured to provide, to the logged-in user, a notification for recommending printing using the decoloring toner, the notification having different contents varying with the decoloring toner use ratio.

A method of controlling an image processing apparatus that is capable of performing image formation on recording sheets, by switchingly using decoloring toner and normal toner, comprising:

• counting the number of sheets printed with the decoloring toner and the number of sheets printed with the normal toner, with respect to the recording sheets, on a user-by-user basis;
• acquiring a decoloring toner use ratio of a logged-in user who has logged in the image processing apparatus, the decoloring toner use ratio indicating a ratio of the number of sheets printed with the decoloring toner to a total number of the number of sheets printed with the decoloring toner and the number of sheets printed with the normal toner, based on counts counted by said counting;
• and
• providing a notification for recommending printing using the decoloring toner to the logged-in user in a case where the decoloring toner use ratio is equal to or lower than a first threshold value.
