    • PURPOSE: An image forming apparatus and a patch detecting method are provided to reduce occurrence of an edge density changing phenomenon in an edge unit of a patch image, thereby detecting the position of the patch image with high precision. CONSTITUTION: Multiple developing units develop latent images formed on multiple photoreceptors by an exposure unit. An image carrying unit makes developed images be transferred. Based on reflective light quantity detected by a sensor, a patch detecting unit detects the position of a patch image (57) formed on the image carrying unit. The patch image has a first area (571,573) and a second area (574) which are formed on the same photoreceptor. The second area is adjacent to the first area. The concentration of the second area is lower than the concentration of the first area. [Reference numerals] (AA) Potential; (BB) Light sensor output; (CC) Threshold value
    • 目的:提供一种图像形成装置和贴片检测方法,以减少贴片图像的边缘单位中的边缘密度变化现象的发生,从而以高精度检测贴片图像的位置。 构成:多个显影单元通过曝光单元开发在多个感光体上形成的潜像。 图像承载单元使得显影的图像被转印。 基于由传感器检测到的反射光量,贴片检测单元检测形成在图像承载单元上的贴片图像(57)的位置。 贴片图像具有形成在同一感光体上的第一区域(571,573)和第二区域(574)。 第二个区域与第一个区域相邻。 第二区域的浓度低于第一区域的浓度。 (附图标记)(AA)电位; (BB)光传感器输出; (CC)阈值
