Abstract

【課題】記録媒体における干渉縞の発生を抑制することができる画像形成装置および画像形成システムを提供すること。 【解決手段】図12に示すように、a≧0.08mm且つb/a<0.80を満たす場合に、干渉縞が発生しない或いは干渉縞が抑制され許容レベルである、という結果が得られた。また、a<0.08mm且つb/a>1.27を満たす場合に、干渉縞が発生しない或いは干渉縞が抑制され許容レベルである、という結果が得られた。 【選択図】図12
PROBLEM TO BE SOLVED: To provide an image forming apparatus and an image forming system that suppress occurrence of interference streaks on a recording medium. SOLUTION: When a≥0.08 mm and b/a<0.80 are satisfied, as shown in Fig.12, a result in which interference streaks are prevented or suppressed in a permissible level is obtained. When a<0.08 mm and b/a>1.27 are satisfied, a result in which interference streaks are prevented or suppressed in a permissible level is obtained. The letter "a" is the advancing distance of a recording medium per gear tooth in a sub-scanning direction orthogonal to a main scanning direction and the letter "b" is a distance by which starting points, from which a pair of dots are formed on a recording medium, are separated in the sub-scanning direction based on a pair of adjacent sub-matrixes of a dither matrix in the sub-scanning direction.
